Update Broadcom Ethernet Drivers

Ethernet connections support high-speed Internet data transmissions traveling over great distances.

If you subscribe to high-speed Internet, such as cable or DSL, then you probably use an Ethernet connection from your PC to the modem or router to get the most out of that service. Broadcom's Ethernet adapters (or "NIC," network interface card) transmit data at speeds reaching 10 Gigabytes per second. All of this speed capability is useless, however, if your Ethernet adapter lacks the correct or updated drivers to communicate with the operating system. Broadcom publishes and releases regular updates to drivers via the company's website so that you can continue to browse and zip along the Internet.

Instructions

1. Open your Internet browser on your computer, then click the link to bring up Broadcom's "Ethernet NIC Driver Downloads" web page (see Resources).

2. Click on the link that pertains to the family and model number of your Ethernet card to advance to the driver page. For example, "NetXtreme II 10 Gigabit" is the family and "57710" is the model number.

3. Find your operating system on the web page and click on the yellow icon labeled "ZIP" to begin downloading the "Broadcom Management Applications Installer." Be sure to save the driver file to a location on your hard drive that you can easily remember such as the desktop.

4. Find the location where you saved the file on your hard drive.

5. Double-click on the file to open it. It is a compressed (.zip) file, so it will go through an extraction process to show the driver files in a window.

6. Click on the folders in the window to open and drill down into the contents. Look for the "Setup" file or use the search box in the window to look for a file named "setup."

7. Double-click on the setup file to open the dialog box that will begin the process of installing the Ethernet drivers. Read and follow the instructions to complete the update for your Broadcom Ethernet driver. Be prepared for a system restart.

Set Up Gigabyte Teaming

Many Gigabyte motherboards include two Ethernet ports, known as dual LAN, with teaming support. When teaming is enabled, the computer can connect to two separate networks and split its traffic between the two, taking advantage of each connection's bandwidth. Teaming also ensures that, if one network goes down or can't access the Internet, the computer automatically uses the other network, preventing any network downtime. Teaming is a feature of the built-in Realtek Ethernet adapter and is configured using Realtek's included utility.

Instructions

1. Insert the Gigabyte motherboard driver disc into your computer's disc drive.

2. Click the "Run Setup.exe" option that appears in the Windows AutoPlay pop-up.

3. Click "Application Software" at the left side of the Gigabyte window that appears, click "Install Application Software" at the top of the window, click the "Install" button under "Realtek Ethernet Diagnostic Utility" and install it by following the instructions on your screen.

4. Restart your computer by clicking "Start," clicking the arrow to the right of "Shut Down" and clicking "Restart."

5. Click "Start," "All Programs," "Realtek," "Diagnostic Utility" and "Realtek Ethernet Diagnostic Utility."

6. Click "Teaming" in the middle of the Realtek Ethernet Diagnostic Utility window and click the "Create Team" button.

7. Type a name for the team into the "Team Name" box.

8. Select the teaming mode your hub requires by clicking it in the "Teaming Mode" list. If you don't know, leave this option as the default "Link Aggregation\LACP (802.3ad)."

9. Click the checkboxes to the left of each Ethernet adapter in the list, and click "OK."

Replace The Fuse In A Laptop Motherboard

Replace the motherboard fuse to get your laptop working again.

If you have tried to turn on your laptop but it won't respond, the fuse next to the power jack could have blown. When this fuse blows out, you will not be able to start your computer. The electrical current will stop at the fuse and not reach the components attached to the motherboard. Changing this fuse is not hard, but you will have to take your laptop apart.

Instructions

1. Remove the battery and unplug the power supply from the laptop.

2. Obtain a disassembly guide for your laptop in order to gain access to the motherboard. Disassembling a laptop varies depending on the brand and the model. Instructions for disassembly are available online or through your laptop's manufacturer.

3. Locate the fuse on the motherboard. This fuse will be just above the power jack.

4. Use a small screwdriver or a pair of needle-nose pliers to free the fuse from the motherboard.

5. Replace the fuse with your new fuse.

6. Put the laptop back together and power it on.

Replace The Battery In An Asrock Motherboard

The CMOS battery powers memory that hold the system configuration settings.

ASRock motherboards have CMOS (complementary metal oxide semiconductor) batteries, which power the memory that holds such information as date and time, passwords and drive configurations. If the CMOS memory loses power, this information is lost. CMOS batteries tend to last two to four years and should be replaced regularly. CMOS batteries for ASRock motherboards can be purchased in computer stores and many general merchandise stores that carry a wide variety of watch batteries.

Instructions

1. Start the computer and enter the BIOS (basic input/output system) setup mode by hitting the "F2" key as soon as the computer starts booting up.

2. Record all settings in the BIOS on each setup tab.

3. Turn off the computer and disconnect the power cord.

4. Remove the case cover from the computer case. This typically involves unscrewing one or two screws and sliding off a part of the case, but this can vary greatly by case design.

5. Locate the CMOS battery on the ASRock motherboard; the location will vary depending on the motherboard model, but it is usually located within an inch or two of the processor. The battery looks like a watch battery and is held in place by a small metal clip.

6. Slide the metal clip sideways off the battery and pull the battery from the holder, noting which side of the battery is facing outward.

7. Place a new battery in the battery holder facing the same direction as the old battery and slide the metal clip over the new battery to hold it in place.

8. Replace the computer case cover and plug in the power cord.

9. Start the computer and enter the BIOS setup mode by hitting the "F2" key as soon as the computer starts booting. Enter and save all the recorded BIOS settings.

Identify My Computer Chipset

Your computer's chipset refers to a collection of chips all located on its motherboard. You may need to know your computer's chipset to do certain firmware upgrades or to locate drivers for it if you don't have your motherboard's original installation software. If your chipset isn't documented on your invoice or in your manual, you will need to open the computer to determine the chipset.

Instructions

1. Set your computer on a good working surface. It should be clean and dry. If possible, when standing or kneeling at the work surface, you should not be on carpet.

2. Open the computer. Many modern computers can be opened simply by pushing a catch or two and sliding the side panel off. If you can't find the catches, check your manual, as this will vary from computer to computer.

3. Try using a screwdriver. Most older computers and some modern ones must be opened with a screwdriver. Look at the back of your computer. Place the side containing your keyboard, mouse, video and printer connectors down on your work surface. Remove the two or three screws fastening the panel on the top and put them carefully aside. With your hand on the back of the computer, slide the panel on top toward you a half inch or until it releases. Lift the top panel away and set it aside.

4. Touch any unpainted metal piece of the computer to ground yourself. You should ground yourself every 30 seconds or so when working with an opened computer. Your motherboard is the large board with a multitude of chips mounted on the computer's remaining side or bottom panel. Find the largest chips on the motherboard. You may need to move some internal components, temporarily, in order to see the chips. As the internal configuration of different computers varies greatly, you should consult your manual for instructions on removing any particular component that's in your way.

5. Record the letters and numbers on the largest several chips of the motherboard. These are usually model or part numbers. The model or part numbers on some chips will be identical; you only need to record each number once. Replace any components you've moved and close the computer when you're finished.

6. Do an online search for the different model or part numbers. The results will tell you what the component in question is. You may need to try more than one model or part number before you get a result that tells you what chipset the component is part of. Write the chipset down.

Identify Memory Chips

All computers need several basic components to run, one of which is random access memory (RAM). RAM provides a computer with short-term memory storage space, where bits of information can be saved temporarily for use in ongoing system processes. The more RAM a computer has, the faster it will be able to load programs and run several programs at the same time. Identifying the memory chips installed in a computer is important both to determine how well the computer is likely to handle certain programs, and how best to upgrade the computer.

Instructions

1. Use the task manager to find out your current memory usage. Windows-based computers can call up a task manager by holding the CRL, ALT and Delete keys at the same time. Doing so brings up a window that displays vital information about your computer, and allows you to perform administrative tasks. After bringing up the task manager, click the performance tab and observe the numbers under "physical memory." There should be an ongoing readout of how much memory is in use, as compared to total system memory. If almost all of your memory is currently being used, you may benefit from adding more RAM to your computer.

2. Run dxdaig command prompt. Another way to quickly find out how much memory is installed on a computer is to run the dxdaig command prompt. To do this, go to the Start menu and click "Run." In the run window, type dxdaig, and click "OK." This will produce a window displaying various information about your computer, including the total amount of memory installed.

3. Download a free memory diagnostic program. For more detailed information about your memory chips, a memory diagnostic is helpful. Crucial, a popular RAM manufacturer offers a free diagnostic tool. CPU-Z is another freeware memory diagnostic tool.

4. Run the diagnostic tool. CPU-Z is an especially useful memory diagnostic tool, as it runs from an .exe file that does not need to be installed onto your hard drive. A memory diagnostic tool will give detailed information about your memory, such as the manufacturer, chip speed, how many memory chips are installed, the size of each chip and possibly even product or serial numbers.

5. Open your computer case and look at the RAM itself. Another way to identify RAM is to open up the computer, lay it on its side and press down on the clips holding in the RAM module to pop it loose. The actual RAM chip should have some information printed on it, such as the size of the module, the manufacturer and possibly a part number or other identifying number.

Retrieve Picture Files Off Broken Computers With External Hard Drive Enclosures

When a computer dies, the two most common culprits are the motherboard and the hard drives. If your hard drives themselves died, then getting files off them is next to impossible. When the motherboard is the part that is nonfunctional, however, you can take out the hard drives and place them in external enclosures. These enclosures convert internal drives into external drives you can plug into any desktop or laptop. Even if your hard drive is clicking or making other unusual sounds, there is still a chance you can retrieve some pictures off the drive before it completely dies.

Instructions

1. Shut off your computer and unplug it from the wall. Open its case and set the case lid or top aside. Locate your hard drive, which in most computer cases are placed at the front of the computer, near the CD or DVD drive. A hard drive is 3.5 inches wide, around an inch or so thick, and has two cables -- one data and one power -- connected to its back. Unplug the cables attached to the backs of your drives.

2. Remove any screws holding the hard drive in the case using a Phillips-head screwdriver. These screws are located on either side of a drive. Some drives, particularly in Dell computers, come on plastic "rails" so you can easily slide the drive out of the case, but you must then remove the rails using a screwdriver.

3. Insert the hard drive into the enclosure, orienting the connector end so that it faces you rather than the bottom of the enclosure. Take the lid to the enclosure and find its cables. Connect these cables to the connectors on the drive. Secure the enclosure lid, which often requires a couple of screws.

4. Plug in the enclosure's power source. Note that not all enclosures require a power adapter, as some get their power through the USB port. Plug your data cable -- typically a USB or eSATA -- into the enclosure and plug its other end into the computer. If the cable is eSATA, look for a port on your computer labeled "eSATA" that looks similar to a USB port.

5. Power on the enclosure or allow it to power itself on if it does not use a power adapter. Go to "Start" and select "Computer." Find the new drive letter and double-click to open your drive's contents. Locate any files with extensions such as JPG, GIF, TIF, PNG or PSD. These are all image file types.

6. Open "Computer" again in a new window and then double-click the drive where you want to place the image files. Line both windows side-by-side or on top of each other. In the window containing the hard drive with your image files, select all image files you want and drag them over to the second window you opened. Depending on the health of the old hard drive, you might need to make multiple attempts before you can get all the files.

Fix A Laptop With Water Damage

The presence of moisture of any kind will affect your computer's ability to work properly. If a computer is used with water damage, the battery could short and cause a bigger problem with your computer's internal components. In addition, this could possibly overload your wall socket and cause a problem with your house lights, and even risk losing power. However, fixing a computer with water damage is not as difficult as one might think.

Instructions

1. Unplug your computer from the wall outlet immediately. In addition, remove the internal battery from its housing on the bottom of your computer. To do this, you need to hold down the release tab located next to the battery pack and slide the pack free from the computer. This is very important so you do not risk getting shocked while trying to fix a water-damaged laptop.

2. Open the computer by first removing all of the screws underneath of the laptop that hold the body together. Next, remove the two screws that hold the laptop screen in place. This will be located not on the bottom, but on the back of the laptop near the power outlet.

3. Remove the hard drive from its slot by unscrewing the two screws from each corner of the drive and sliding it free from the computer. Make a note of the way you removed it, because if you put it back in upside down, the computer will not work. Check the hard drive for moisture. If moisture is present, press down with a towel to remove any immediate moisture, but do not wipe the hard drive as this may move the moisture around instead of removing it. Blow dry any additional moisture that remains.

4. Separate the laptop screen from the body by gently pulling up on the screen until the two silver pegs have been removed from their slots. Make sure not to disconnect the two wires that lead from the screen to the motherboard. Separate the two halves of the plastic body to uncover the computer's internal components.

5. Unscrew the metal plate that covers the motherboard and set it aside. Take pictures of the inside of the computer so that you will have a frame of reference when reinstalling all of the components. Start by taking an overview picture of the whole thing, then closeup pictures of the individual items.

6. Disconnect the components one at a time and begin drying them in the same manner as you did the hard drive. After drying completely, let the components sit out overnight to air-dry as well.

7. Reinstall all of the components the exact way you removed them, and refer back to the pictures you took in step 5 so that you are reinstalling everything correctly. Reinsert the battery pack and turn the computer back on. If nothing was irreparably damaged, your computer should be functional again.

Fix A Motherboard For Laptops

Laptop computers integrate most of the internal components right onto the motherboard.

Motherboard repair for laptop computers is a complex process that involves removing the motherboard from the computer and troubleshooting the specific component that has failed. The individual component can be replaced on some boards, but in many cases it is impossible to repair the board and it must be replaced. Learn locate and repair broken connectors and solder small surface-mount components on a laptop motherboard when they are obviously the source of the problem, as is the case with a liquid spill.

Instructions

1. Power off the laptop if it is on and close the lid. Remove the power cable and main battery along with any cables or accessories that are attached. Remove the laptop from any docking station or sleeve that may be in use.

2. Remove the compartment covers for the RAM and hard drive. Spread the retention clips on the RAM modules and pull them straight out of the system at the 45-degree angle they spring up to when released. Remove the hard drive by sliding it away from the connector slightly and lifting it out of the system. Remove any screws that may be holding the hard drive in place.

3. Remove all of the screws from the bottom of the laptop. Flip the laptop right-side up and open the lid. Remove any trim ring or trim strip along the keyboard with the plastic knife or credit card. Remove the screws that hold the keyboard in place. Gently lift one edge of the keyboard up and slide the other edge out, and lift the keyboard up about an inch out of the system. Release the cable clamp on the motherboard that holds the keyboard and touch pad cables in place and remove the keyboard assembly from the laptop. Remove the VGA cable standoffs from the rear port section of the laptop along with any other standoffs or screws that hold the motherboard in place.

4. Remove any accessible screws from the motherboard and slide the optical drive out of the system. Disconnect any cables or connectors that attach to the motherboard and loosen any cable guides or clamps that keep cables in place along the surface of the motherboard.

5. Slide the edge of the plastic knife or credit card along the seam between the upper and lower halves of the chassis to open the case. Remove the top or bottom of the case, depending on the specific model of laptop being worked on.

6. Remove any other screws or cables that are attached to the motherboard, and lift the motherboard out of the system.

7. Dip the small, stiff cleaning brush into the 91% Isopropyl alcohol and scrub any spill stains from the surface of the motherboard. Wipe down and touch up with a lint-free cloth and cotton swabs.

8. Preheat the electronic soldering iron. Touch the solder-braid copper solder remover to the first soldered contact of a component that is obviously damaged. Press the tip of the soldering iron against the solder-braid copper solder remover for about three seconds until some of the solder is absorbed into the braid. Lift the iron and the braid away from the component and wait a few seconds for the heat to dissipate. Repeat for the same connection if necessary, and then repeat for other connections for the same component until the component lifts off the motherboard.

9. Line up the replacement part exactly and press the tip of the soldering iron to one contact and quickly touch the tip of the lead-free solder to the connection until a small amount of solder melts into the connection. Remove the solder and soldering iron and inspect the connection. Repeat if necessary for the connection or use the solder-braid copper solder remover to absorb any excess solder. Continue to attach the component until each connection is complete.

Install A Display Adapter

A display adapter is a computer hardware device that is responsible for processing and sending images to a monitor, which can also be called a video card or graphics card. Installing a new display adapter can increase a computer's ability to process complex graphics, and can also allow the computer to connect to different devices using the ports on the back of the display adapter. Installing a display adapter requires physical installation inside your computer's case and setting up display driver software.

Instructions

1. Shut down your computer and unplug all cords from the back.

2. Use your screwdriver to remove the screws along the right side of the back of the case to release the case's side panel. Usually this requires taking out three screws with a Phillips head screwdriver, but depending on your case, you may need a Flathead screwdriver.

3. Set the side panel that you removed aside, and then lay the case down so that you can easily look into it at the motherboard.

4. Locate the appropriate slot to install your display adapter. Video cards are usually installed in AGP or PCI express slots, which are usually the highest slots in a column of descending parallel ports along the lower left corner of the motherboard. You can determine the appropriate slot by comparing the size of the card's plug--the end with gold-tipped connectors--to the size of the slots on the motherboard.

5. Remove the slot cover with the appropriate screwdriver. At the back of the case behind the AGP or PCI express slot, you will probably have to unscrew a metal slot cover to make room for the video card. They screw holding on the cover will usually be a Phillips head screw.

6. Plug the video card into the open slot. Start by aligning the card squarely in the slot, with the ports of the card lined up where the slot cover used to be. Push the card firmly into the the slot, making sure pressure is directed perpendicular to the motherboard so that the card does not bend one way or the other. The card should pop into place.

7. Close the case, plug the cords back in and power on the computer.

8. Insert the driver installation CD that came with your display adapter.

9. Open the driver CD and run the driver installation executable file. (Inserting the CD may cause the process to begin automatically.) Wait for the driver install process to complete, then restart your computer.

Make Your Own Chip Puller

Large, modified paper clips work well as chip pullers.

A chip puller is a simple, tweezer-type tool that helps you remove a chip from an electronics board, such as a motherboard, without breaking or bending the pins that hold it in place. Sometimes it is easier to use a homemade chip puller instead of a standard chip puller because you can customize its tips to the chip socket size and the angle at which the chip is seated.

Instructions

Paper Clip---One-Sided Chip Puller

1. Unbend a large paper clip until it is in a straight line.

2. Use pliers to strip back the rubber or plastic coating on one end of the paper clip until about 1/4 inch of wire is exposed.

3. File the exposed metal end with a metal file until the end has a point that will get under a computer chip to pull it from an electronics board.

4. Shape the exposed wire with the pliers so that your chip puller end is angled. This will help you pull a computer chip up and out of its pin setting on an electronics board.

Paper Clip---Double-Sided Chip Puller

5. Align the wire cutters on a large paper clip so that you cut through it slightly below where the inner bend ends. The inner pieces should fall out. You should now have an open-ended oblong shape like a pair of tweezers.

6. Use pliers to strip back the rubber or plastic coating on the paper clip ends until about 1/4 inch of wire is exposed on each end.

7. File the exposed metal ends with a metal file until each end has a point.

8. Shape the exposed wire with the pliers so that your chip puller end is angled. This will help you pull a computer chip up and out of its pin setting on an electronics board.

Tweezers

9. If you need a stiffer chip puller for more difficult chip pulling, use a metal file to file the ends of lightweight, soft metal tweezers into sharp points.

10. Bend the tweezer sides inward or outward with pliers, depending on the size of the computer chip, to aid in gripping the chip's sides.

11. Bend the tweezer tips inward at an angle that will help you get underneath a computer chip to pull it out.

12. Wrap thin strips of duct tape around the handle and sides of the tweezers to give you a better grip.

Open A Dell Optiplex Gx280 Tower

To install new hardware in your Dell OptiPlex GX280, you will need to open its tower first.

The Dell OptiPlex GX280 computer comes in five different form factors with three different, but similar, methods for removing the case. Identify whether you have a "Small Form Factor," "Small Desktop," "Desktop," "Small Mini-Tower" or "Mini-Tower" system by clicking on the link in the "Resources" section of this article. There are three opening methods for Dell OptiPlex GX280 towers, and the method you choose is dependent on the type of tower you have.

Instructions

1. Unplug the cables from the back of your OptiPlex GX280. Wait at least one minute before opening the case in order to allow the capacitors inside to completely discharge any electricity. Set up the case where you have room to open it, such as on top of a desk.

2. Open the "Small Form Factor" and "Small Desktop" cases by locating the two release buttons, which are located near the back of the computer on the narrow ends. Press them at the same time, then lift the side of the case up. Pivot the back of the case up toward the front.

3. Open the "Desktop" and "Mini-Tower" cases by setting the computer down on its side so that the release latch is facing up. Slide the latch while you lift the side of the case. Pivot the side until it comes free of the anchor points, then lift the side away and set it aside.

4. Open the case of the "Small Mini-Tower" by setting the computer on its side, ensuring that the power cable port is closest to the ground. Press the release button on one side of the computer, then lift the side with the other hand. When the first release button is free, press the release button on the other side and lift the side of the case to free the second button. When both release buttons are free, hold down the case while you lift the side of the case off.

Replace An I5 With An I7

Boost performance with a CPU upgrade.

The Intel "iCore" processors were released in 2010. There are three versions of this processor: the i3 dual-core, i5 quad-core, and the i7 quad-core with hyper-threading. Hyper-threading provides four virtual cores, so the computer sees eight cores. The first generation of these processors uses Socket 1366 and 1156 motherboards, and is not interchangeable. The second generation Sandy-Bridge processors use the Socket 1155 motherboard and are not interchangeable. You can get a significant performance boost by replacing your i5 with an i7 processor, and do it in less than an hour.

Instructions

1. Turn off the computer. Remove the power cord from the power supply. Disconnect all devices that are connected to the computer. Use a Phillips screwdriver to remove the two screws from the rear of the left -- as you look at the computer -- side cover. Slide the cover back and remove it.

2. Lay the computer on its right side so you can look down into the case. Before reaching into the case, touch an unpainted part of the case to prevent any static discharge. Trace the power cord from the cooling fan on the CPU heatsink to the motherboard. Disconnect the cord from the motherboard.

3. Locate the four push-pins that hold the heatsink assembly onto the motherboard. Note the orientation of the heatsink assembly so you can put in back in the same position. Carefully pull out on the pins until they disengage from the holes in the motherboard. Lift the heatsink assembly from the CPU.

4. Disengage the load plate that retains the CPU. Move the arm on the side of the plate a little bit to the side to unhook it from the plate and lift up the arm. This will lift the load plate up halfway. Gently grab the plate and rotate it until it is even with the arm.

5. Note the position of the CPU in the socket. There are two notches in the CPU that match two tabs in the upper portion of the load plate. Carefully lift out the i5 CPU. Use a paper towel dampened with isopropyl alcohol to clean the thermal paste from the top of the CPU. Clean the base of the heatsink assembly in the same manner.

6. Gently lower the i7 CPU straight down onto the socket. Be careful not to bend any of the fragile pins on the socket. Make sure the notches are in the same position as the old CPU. Make sure the CPU is seated flat on the socket. Lower the load plate and arm over the CPU. The end of the arm will fit into the end of the plate to lock it into position.

7. Place a dab of thermal paste -- about the size of a small pea -- on top of the CPU. Line up the pins on the heatsink assembly with the holes on the motherboard and lower the heatsink onto the CPU. Push one of the heatsink pins into the motherboard until you hear a "click" that tells you the pin has fully engaged the hole in the motherboard. Push in the pin directly across -- not next to -- the pin you just installed. Repeat for the other two pins.

8. Plug the fan connector into the motherboard. Note that it will only go in one way. The motherboard has a tab that fits into a slot on the connector.

9. Stand up the computer. Reconnect any devices that you removed. Plug the power cord back into the power supply. Turn on the computer. Make sure the fan is running. Turn off the computer. Reinstall the side cover.

Fix A Short Circuit On A Computer

The power supply can be the cause of a power problem, or short circuit, with your computer.

The term "short circuit" is meant to describe an exact electrical situation in which there is a low resistance connection between two nodes. The term is often misused, because it is often used to describe almost any electrical problem. When a computer short-circuits, it usually means something inside isn't connected properly, related to the power supply. If the motherboard isn't connected properly to the case, it can create a short circuit. There are a few possible solutions, though if the simpler options don't solve the problem, the power supply might need to be entirely replaced.

Instructions

1. Test your computer's power supply by plugging it in to another power strip or another outlet.

2. Unplug the computer. Open your computer case by unscrewing the access door from the back of the computer. You might have to push a button or release to remove or open the door. Then, use a can of compressed air to blow the dust out of the computer, including the fans and around the motherboard.

3. Check to see if any computer parts are loose. Make sure the motherboard is screwed in all the way. Unscrew the CPU fan and heatsink, lift the CPU bar and remove the CPU. Reseat the CPU, making sure the corner with the missing pin and missing hole in the CPU and CPU socket match.

4. Replace the power supply as a last resort. Disconnect the power supply from the motherboard and all of the drives/hardware that have power connected to them from the power supply. Unscrew the power supply from the back of the case and lift it out. Replace with a new power supply, then reconnect the power to the motherboard and any other hardware that requires a power connection.

Upgrade Your Psp Firmware

Upgrading your PSP's firmware is important for keeping your unit up to date with the latest drivers, applications and so on. Every so often, Sony releases a firmware upgrade exclusively for the PSP, but it is your job to upgrade your device. There are two ways you can accomplish this: through direct download to the PSP via a wireless Internet connection or through PC download. I will go over both methods for upgrade your PSP firmware.

Instructions

Upgrading Your PSP Firmware Using WiFi

1. On the lower left-hand side of your PSP, you will notice a little silver slider. Slide the switch up and this will turn on the WiFi feature on the PSP. Of course, you do need a home WiFi setup for this to work. Your battery also needs to be full. Even if your battery is low and your unit is plugged in to an outlet, the firmware upgrade may not work.

2. With a fully charged device, go to your PSP's home screen and choose "Network Update."

3. This screen will ask you for your WLAN settings. Choose "Scan" and let the PSP detect the network automatically. Choose the right one and keep all of your settings in the default stage. Press the "X" button and the PSP will save the configuration as your new access profile.

4. Choose it again and when your PSP connects to the network, and if there is an update available, you will automaically see the following message: "Network Update has found a later version. To download, insert a Memory Stick with at least 14MB of free space and press the X button."

5. Press the "X" button and you should see the message: "Downloading." IMPORTANT - Do not turn off your PSP or remove the memory card during this time!

Replace Motherboard Parts

A computer motherboard

When you own a personal computer, it doesn't always measure up to your expectations. Sometimes there are features that you want to upgrade or items that you want to add on for enhanced functionality. Oftentimes, this requires the replacement or addition of parts to the motherboard of the computer. It would not be recommended while the computer is still under warranty, but many users decide to upgrade or repair their own computers successfully.

Instructions

1. Disconnect the power cable from the computer. Any time you work inside of the computer, this should be the first thing you do.

2. Remove the side panel from the computer by unscrewing the retention screws on the back. You will need to use the Phillips head screwdriver unless your computer is equipped with thumb screws that can be turned by hand.

3. Attach an ESD wrist strap to your wrist and secure to the chassis of the computer. This will help reduce the chance of you damaging any of the sensitive computer chips with an electrostatic discharge. If an ESD wrist strap is unavailable, ground yourself to the chassis by grabbing it with one hand to discharge any static electricity and equalize the charge between you and the machine.

4. Remove the motherboard parts that you are going to replace. There are quite a few items that are considered field replaceable units (FRUs). These items could include memory modules, the CPU, CPU fan, sound card, video card and more. Of course, when replacing bad parts on the motherboard, you will have the new part to compare and help locate the part you are going to replace. If you are upgrading or adding functionality, this will not always be the case.

5. Replace the motherboard parts that you removed with the new replacement parts. It is important to always be gentle with the motherboard and never force a part into place. For example, the CPU has a pin configuration that only fits into the socket one way. If you break a pin on the CPU, it will no longer work. If too much force is used in inserting memory modules into the memory slot, it is possible to crack the motherboard. If this happens, the mother board itself would need to be replaced.

6. Reassemble the computer in the reverse method from which you took it apart. Be sure all old parts are removed and the cover is back and secure before plugging the electrical cord back in. Some parts may require the installation of new drivers. These drivers are typically supplied by the manufacturer in the form of a CD-ROM that comes with a new part such as a video card or sound card.

Remove A Processor From A Motherboard

The processor, or CPU (central processing unit), is the brain of a computer, responsible for carrying out the calculations that allow a computer to function. The processor is one of the more expensive components of a computer and is therefore somewhat less economical to upgrade than cheaper parts like disk drives, hard drives and RAM. Still, being able to remove a CPU can be useful, both for upgrading or moving a CPU from one computer to another.

Instructions

1. Power off the computer and unplug the cords.

2. Open the computer case with a screwdriver. Set the computer down on its side, so that that the motherboard is easier to see.

3. Unscrew, and unfasten the heat sink and fan. With the computer open, you will notice a large fan attached to the motherboard on top of a network of metal fins called the heat sink. This is the CPU fan, which is located directly above the processor. Fans and heat sinks differ somewhat in how they are fastened, but most require either a few screws to be taken out, or some securing clips to be opened.

4. Take the fan and heat sink out and set them aside.

5. Release the CPU locking mechanism. Now you should see the square shaped CPU, which will be held in place by a plastic or metal locking level. Pull the lever up to unlock the CPU

6. Remove the processor. With the locking level open, pinch the CPU with the thumb and forefinger and and remove it from its slot.

Install Pci Graphics Card In A Dell Optiplex

A Dell OptiPlex 745.

The Dell OptiPlex has basic video graphics components built into the motherboard. Often, users upgrade this basic graphics support with advanced expansion cards. Many high-end expansion cards come in a specialized format known as AGP. However, older lower-end expansion cards run on the PCI expansion slots and are still used in the OptiPlex. Depending on the form factor, the Dell OptiPlex provides between two and four PCI expansion slots that can be used for this upgrade.

Instructions

1. Turn off the computer and unplug the power cord. Remove all connectors from the back of the unit and label them accordingly with tape if they are not color-coded.

2. Open the case using the thumb screws located on the back of the unit.

3. Disengage the locking arm that holds the expansion cards in place on a mini-tower. This is not present on the smaller form factor. Insert the new expansion card carefully into an open PCI slot. The card must sit firmly in place but not be forced. The outward-facing part of the card must align with the open slot.

4. Replace the locking arm and close the case to hold the new PCI card in place. In the smaller-form-factor OptiPlex, use the provided screw to secure the PCI card to the computer chassis. Next, close up the case and secure using the thumbscrews. Re-attach all cables and power cords to the back of the computer. Attach the video cable from your monitor to the output from the new PCI graphics card you just installed.

5. Power up the computer and install graphics card software. Depending on the operating system installed in the system, it may automatically recognize and install software for the video card. However, it is best to install the manufacturer's provided software and then check the manufacturer's website for any updates to the drivers for the card in question.

6. Finally, reboot the computer to complete installation.

Repair Bios

The BIOS is a set of instructions written on a chip.

Repairing the BIOS on the motherboard is usually a matter of updating the BIOS in a process called flashing the BIOS. The BIOS is a set of instructions written to a chip called an EPROM, or erasable programmable read only memory. The BIOS gives basic instructions on how the operating system communicates with installed hardware. Flashing BIOS can allow support for new components not previously supported, such as a different type or brand of drive. If the BIOS becomes corrupted by a virus or other malicious program or error in settings, flashing the BIOS can restore the computer to proper working condition.

Instructions

1. Power down the computer, unplug the power cord and press the power button to discharge all current.

2. Open the case and write down the motherboard manufacturer and model. This will be printed on the motherboard in larger type and easy to locate.

3. Boot your system. Write down the BIOS manufacturer, version and date. You may have to reboot a couple of times as this information flashes on the screen pretty quickly.

4. Go to the motherboard manufacturer's website and download the newest BIOS software onto the USB flash drive. There may also be a program for flashing the BIOS available; download this program as well. The program will be compressed and needs to be extracted to the USB flash drive.

5. Reboot the computer. As the computer is booting, press the key required to enter setup. The correct key varies from board to board.

6. Look for the boot order under the "Advanced" settings screen of the setup program. Change the boot order to allow the DVD drive to be the first boot drive. Save and exit setup.

7. Reboot the computer with the Windows 7 install disk in the DVD drive.

8. Locate the flashing program on the USB flash drive and double-click the file to run it. If you are prompted to back up the old BIOS, select "Yes." If the system becomes unstable or other problems arise after the BIOS update, you can revert to the old BIOS.

9. Reboot the computer and enter setup as you did earlier. Select the option to set all BIOS settings to default. Save, exit and reboot the computer. Check that everything is working properly.

Look For Gold On Circuit Boards

A printed circuit board has tiny traces of metal including gold that a person can extract.

Circuit boards are the heart of a computer system. In many cases, the circuit boards have tiny amounts of metals such as gold, silver, copper and lead. These metals are used to improve conductivity. Although the gold is in small amounts, you can extract the metal from printed circuit boards. While you won't get rich removing gold from circuit boards, some people enjoy the challenge.

Instructions

1. Gather all the circuit boards you have, and place them in a pile. Some people purchase old circuit boards, while others collect them from old computers.

2. Break the printed circuit boards into smaller pieces with your hands.

3. Break or mill the printed circuit boards into tiny fragments. A few options exist for breaking up the circuit boards into small pieces, such as a wood chipper. But smaller and more convenient options are an electronic mill or a hammer mill.

4. Place the small circuit board pieces into the electronic or hammer mill.

5. Turn on the machine. The mill refines the circuit board pieces into pieces as small as a grain of rice.

6. Empty out the contents of the mill onto a piece of paper.

7. Wave a metal detector over the contents, to detect and separate the metals from the rest of the circuit board pieces. Search through the metal, to find the gold which is yellowish in color.

Fix A Laptop Power Connector

A failed power connector on a laptop is replaceable with some expertise.

A failed power jack or connector on a laptop ends the computer's usable life until it is replaced. If you have soldering experience and know your way around under the hood of a laptop, this is a repair that you can do yourself. The parts are inexpensive and the method is simple if you have a good relationship with a soldering iron. Follow these steps to fix a laptop power connector.

Instructions

1. Power down the computer and remove the power cord. Slide the battery lock tabs on the back of the computer and remove the battery.

2. Unscrew all the screws from the back of the computer case. Set them aside on a strip of the masking tape so they don't get lost. Lift the cover from the laptop gently, undoing any clips holding it in place.

3. Remove the motherboard from the computer and locate the power jack. It will be soldered to the motherboard.

4. Add some new solder to the solder connections between the motherboard and the power jack. This will heat the existing solder and make removal easier.

5. Heat each of the contacts with the soldering iron. Use the de-soldering pump to remove as much solder from each contact while heating it. Repeat with all the contacts until you have removed as much solder as you can.

6. Attempt to remove the power jack from the motherboard. There may still be solder connecting them, so wriggle it gently while heating the contacts one by one to release any solder. Do not force the removal as you can damage the terminals on the motherboard.

7. Apply a fresh coat of solder to the connectors on the new power jack. Using a toothbrush and the alcohol, remove any flux from the connectors on the motherboard and apply a fresh coat of solder to them as well.

8. Replace the power jack on the motherboard. Stabilize the motherboard and jack with something propped beneath it if necessary to avoid any gaps when soldering. Begin re-soldering the contacts.

9. Reinstall the motherboard with the new power jack. Replace the computer cover, install the battery and connect the power. Your laptop should now be ready to use.

Fix The Bios In Windows Xp

The BIOS, otherwise known as the "Basic Input Output System," is the most basic operating system on your computer, stored not on your hard drive but on a small chip physically located on the motherboard itself. Repairing a BIOS can be tricky, involving a substantial amount of time and heartache on your part, but it can be accomplished. There are a number of methods that can be used to fix a BIOS under Windows XP, so start with the easiest and work your way up to the complex.

Instructions

1. Consult your motherboard instruction manual to determine whether there is a backup BIOS chip on your motherboard. A number of modern motherboards contain a second BIOS chip that can be used when the initial chip is experiencing errors, preventing an outright computer failure. If your board has such a chip, follow the specific instructions contained in the instruction manual to refresh the broken chip with the good version of the BIOS stored on the backup.

2. Go online with another computer in the house, and download a copy of the BIOS for your particular motherboard. Be sure you know the make and model of the motherboard correctly, as a BIOS is often individual to a particular motherboard, and you could cause further problems by downloading the wrong one. The motherboard version is often contained in the documentation for the PC, but if all else fails you can call up your manufacturer and ask for your specific model. Once you have the correct copy, save it to a flash drive or floppy disc (3.5") and reinstall it on your broken computer by using the specific BIOS installation instructions contained in your computer's operating manual.

3. Contact the manufacturer of your motherboard or PC about the possibility of ordering a new BIOS chip. Once you have a new BIOS chip, you can physically replace the defective chip, restoring your computer to full working order. Note that a computer hardware repair shop can perform the operation for you if you do not feel comfortable working on the innards of your PC.

Install A Micro Atx Motherboard

Installing a motherboard is quite possibly one of the most important computer installations a computer owner can have knowledge of. Micro ATX motherboards are a form factor motherboard designed for small footprints over raw system performance. Despite the importance of the computer motherboard and its installation, it is surprisingly easy to install one with little or no experience in just a few minutes.

Instructions

1. Screw the riser pins that came with the motherboard into the computer case. There will be predrilled holes in the computer case for these pins, and the motherboard will detail which holes need riser pins. Though Micro ATX follows a form factor, not all mounting pins are always used by a motherboard, and, as such, one should refer to the documentation to ensure that she is installing risers in the right position.

2. Take the "back plate" for the motherboard and press it firmly into the back face of the case. This back plate provides apertures for the computer's I/O components, such as USB, mouse and keyboard connectors. The back plate will come with the motherboard and fit into the rectangular hole in the back of the computer case snugly.

3. Lay the motherboard inside the case, taking care to align the mounting holes on the motherboard with the previously installed riser pins.

4. Insert and tighten one screw per riser pin. The screws will screw into the riser pins, providing a secure mounting for the motherboard, while separating it from the metal mounting plate. When tightening these screws, it is important to make sure they are tight enough to hold the motherboard in place without being so tight as to put undue stress on the motherboard.

5. Connect the computer case's power, reset and hard drive connectors to their respective power pins on the motherboard. These pins are labeled for easy identification and are found near the bottom-right corner of the motherboard.

Fix A Button On A Laptop

Check underneath the button to make sure none of the hinge components are missing.

It's only a matter of time until a key on your keyboard decides to go rogue. Keyboard keys are only attached by a few tiny hinges and a bit of glue, so don't fret when one comes loose or starts to wobble. Check the components of the button to make sure nothing is broken. If any parts of the key or hinges are broken or missing, you may need to order replacement parts.

Instructions

1. Unsnap the key next to the button that needs repairing. Pry the button up with your fingernail or tweezers by pushing it from front to back. Don't worry if you need to use a little force but try not to rip the button off too hard. You don't want to lose any components by sending them flying across the room.

2. Look at the key spot that you just removed the button from. Notice the two plastic hinges that hold the button in place, and the little rubber cup in the center that gives the button its bounce. If any of these components are missing from your broken key, you will need to order parts to fix it properly (see "Resources").

3. Lay the hinges down onto the broken key spot exactly as they appear on the key next to it. There are four connections where the plastic retainer hinges on the keyboard. Set each corner into the notches on the keyboard and replace the key cap by setting it in place and pressing down until it snaps.

Replace A Dual Core With A Quad Core

Make sure your motherboard is compatibe with the particular quad core CPU you plan to install.

Replacing a CPU can make a noticeable change in your computer's performance, and replacing a dual core processor with a quad core processor may be an attractive option. More cores do not necessarily mean better overall performance, but for machines running multiple complex applications, quad cores may help software run more quickly and with greater stability.

One of the most important steps in upgrading a processor, whether or not the processor has the same amount of cores, is ensuring that your replacement processor is compatible with your motherboard. So consult your computer or motherboard documentation before upgrading to any new processor.

Instructions

Access

1. Turn off your computer and unplug all the external wires.

2. Remove the computer case or side panel, depending on your computer. You will usually have to loosen or remove screws at the back of the case first.

3. Ground yourself with an ESD wrist strap that attaches to bare metal spot on the computer chassis. If you don't have an ESD wrist strap, touch an unpainted metal surface inside the case before you start, and again frequently as you work inside the computer.

4. Remove the motherboard from the case if necessary. The motherboard attaches to the case with screws. You will probably be able to replace the CPU without removing the motherboard, but removing it will give you better access.

Replace

5. Remove the heat sink. The heat sink may be secured with a latching mechanism or by small screws or securing posts that release the heat sink when turned.

6. Flip up the lever on the side of the CPU socket to release the old processor, and remove it by pulling it straight up and out of the socket.

7. Grip the new CPU by the edges, align it with the socket and push it into place. Then flip the lever to secure it.

8. Apply thermal grease to the top of the processor. Your processor documentation should explain apply it, but it is usually applied to the center of the chip.

9. Press the heat sink down onto the processor. This will spread the thermal grease. Secure the attaching mechanism to the heat sink.

Reassemble

10. Replace the motherboard into the CPU case and secure it with screws if it was removed.

11. Close and secure your computer case.

12. Plug the external wires back into the computer and turn the power on.

13. Enter your system BIOS according to your motherboard instructions. This is usually done by pressing one of the function keys during start-up. You'll have to set the BIOS for your new CPU.

Fry A Motherboard

A computer's motherboard holds all of its start up instructions and a matrix of complex circuitry. This flat piece of material contains all of the instructions for handling video, audio and routing information for the computer's peripheral devices, such as CDs, DVDs and card readers. Sometimes events happen that render the motherboard useless, or fried.

Instructions

1. Open the case while the system is running. This is an industry standard "no-no," and the introduction of debris and foreign matter into the case is a typical way to fry a motherboard.

2. Spill even a small amount of liquid into or onto the computer case. Any liquid that enters the case containing the motherboard will cause a multitude of errors and eventually destroy the circuitry.

3. Introduce an electrical current to the computer's power supply that exceeds the power supply rating. Electrical spikes are the most common manner in which motherboards fry. Surge protectors are a must to keep the computer's motherboard safe.

4. Turn off the computer system's anti-virus software. Anti-virus software helps to keep out malicious code from entering the operating system. By turning this protection off, the motherboard is vulnerable to attack and damage.

5. Disable the computer system's fans or cooling system. The heat generated by the operation of the computer is enough to literally melt components on the motherboard.

Instructions

1. Unplug the computer and the cable connecting the graphics card to the monitor.

2. Lift off the top of the computer, and find the old graphics card.

3. Determine the type of slot on the computer's motherboard being used by the graphics card. It is either AGP (which is longer than the other slots), PCI (which is a "half-size" slot), or PCIE (which looks like a PCI slot, but is set further back on the mother board).

4. Purchase your new card, making sure it is compatible with the video slot on your computer's motherboard.

5. Unscrew the tab attached to your computer case that is holding the card in place.

6. Pull the old card straight up without hitting any of the other components in your computer.

7. Install the new card by gently pushing it into the slot vacated by the old one and screwing its tab onto the computer case.

8. Test the new card before putting the cover back on the case.

Fix A Flickering Laptop Screen

Laptop screens are prone to several display problems.

Laptop computers have LCD displays that are sensitive to many things. LCD displays have faults that sometimes produce a flickering screen, lines, dots or a faint display. These screens are sensitive to magnetic fields or electronic items near the computer. Speakers, cell phones, lights and other electrical items are examples. Your display also could be flickering due to software issues such as the video drivers or hardware issues relating to a faulty inverter or the LCD screen itself needing to be replaced. Trace the cause of your problem to come to a resolution.

Instructions

1. Turn off the computer. Disconnect all external devices. Turn the computer over (bottom facing up). Take out the battery and reseat it. Turn on the computer.

2. Reset your resolution and refresh rate by right-clicking the desktop and selecting "Screen Resolution." The "Change the Appearance of Your Display" dialogue box appears. From the "Resolution" drop-down list, select the recommended resolution of your display. If you don't know the recommended resolution, refer to the product manual. Click the "Advanced Settings" link in the lower right. The graphic card dialogue box appears. Click the "Monitor" tab. From the "Screen Refresh Rate" drop-down list, select "60 Hertz." Click "OK."

3. Check your computer's surroundings. Move away speakers, fluorescent lights, fans, cell phones, radios and other electrical devices that can cause flickering. Temporarily move electrical items away from the computer to determine whether they are producing this issue.

If the flicker stops, put back one item at a time to determine what is causing the problem.

4. Connect an external monitor to your laptop computer to determine whether that screen also flickers. If there is no flicker, then the problem is strictly with the laptop, indicating a possible hardware failure. Contact the manufacturer for a replacement LCD.

If the flicker continues, proceed to the next step.

5. Reinstall the video driver. To do so, log in to an administrator account. Then navigate to the "Start" menu and right-click "Computer." Select "Properties" from the drop-down list. From the left pane of the dialogue box, select "Device Manager." From the Device Manager, double-click "Display Adapters." Double-click on your graphics card, select the "Driver" tab and select "Uninstall." Then reboot your computer. Device Manager reinstalls the video driver. Verify whether your display's flickering has stopped. If not, proceed to the next step.

6. Navigate to the manufacturer's website. Download and install the newest video driver and BIOS for the computer. Restart the computer after the drivers are installed. Continue to the next step if there is still flickering.

7. Carefully open up your display screen all the way. If the flicker stops by opening it a certain distance, the display inverter is faulty. If the flicker still exists, the LCD screen should be replaced.

8. Contact the manufacturer of the computer for more information and a possible replacement inverter. This will depend on the manufacturer and the computer itself.

Fix A Gateway Solo Laptop

Like any complex piece of equipment, your Gateway Solo laptop will likely require maintenance at some juncture.

Fixing a Gateway Solo laptop can be a tricky process due to the myriad problems that can afflict your machine. However, many of the most likely problems on a Gateway Solo laptop can be repaired by anyone, regardless of computer experience and with only a Phillips head screwdriver. With your screwdriver in hand and a bit of patience, your Gateway Solo laptop can be fixed in short order and back to a working, functional capacity.

Instructions

1. Turn off the Gateway Solo laptop and check its battery, which deteriorates over time (generally after 1000 charges on average) and may need to be replaced. Flip over the laptop and locate the battery's outline, which will be a horizontal compartment generally at the top center of the device, depending on your precise model. Right below the battery is the battery release mechanism, which when disengaged will pop out the battery.

2. Replace the keyboard if it ceases to function. Flip over the laptop and locate the keyboard-related screws on the back, which can be removed with a Phillips head screwdriver. These screws should be indicated by a small, keyboard-shaped icon.

3. Turn the laptop back over once the screws are out and remove the keyboard shield, which is located just above the keyboard and just below the display. Use a flat head screwdriver as a simple flat object to wedge under the ends of the shield to pop it off gently.

4. Pull the keyboard partially out to reveal the cable that runs from the bottom of the keyboard to the keyboard connector at the base of the Gateway Solo laptop. Pop this connector from its flat, horizontal position upward into its upright position, then pull the cable from it and remove the keyboard altogether.

5. Consider replacing the Gateway Solo laptop's screen if there is a display issue that cannot be repaired by adjusting monitor brightness settings or restarting your computer. Begin by taking out the screws that surround the laptop bezel and then popping off the bezel and removing it. With the bezel removed, two brackets on either side of the screen can be seen, with screws in each. Use the Phillips head screwdriver to remove these bracket screws.

6. Notice the inverter cable, which is located just below the screen. The inverter cable connector holds the inverter cable in place. Slide it into an upright position to disengage the inverter cable. The screen will be freed and can now be completely removed and replaced as desired. When reinstalling, remember to re-attach the inverter cable and all associated screws in the process.
