Replace your computer's motherboard.
If your desktop computer was an automobile, the motherboard would be its frame. It's the largest internal part of the PC, and it connects everything to everything else. The power supply, CPU, hard drive, disk drive, RAM, graphics card and sound card all connect through the motherboard. Because of its complexity, the motherboard is also one of the most common parts of a computer to fail. Removing the K8N8X-LA motherboard from your desktop and installing a new one will require extensive work and should not be attempted by a computer hardware novice.
Instructions
1. Turn your computer off and remove all power and data cables. Place the computer on a clean, steady table with the case's access panel facing up.
2. Remove the access panel screws from the back of the case with a large Phillips-head screwdriver. Slide the access panel back, pull it off and set it aside.
3. Unplug all the power and data cables from the motherboard except for the processor and CPU cooler. These cables you will remove in this step, in any order, are: the 20-pin motherboard power cord, 4-pin CPU power cord, 2 SATA data cables (hard drive and CD drive), the front USB cord, front audio cord and front power/LED cable. There also may be system cooling fans connected to the motherboard. Remove the power cable attached to the graphics card if it is present.
4. Remove all the screws holding the motherboard in place. Remove any screws from any other attached components, such as the graphics card. Remove any components obscuring the motherboard except the CPU fan, the RAM DIMMs and any AGP or PCI-E cards. Grasp the motherboard and pull it out of the case. Carefully set it on the table. Put the case on the ground and place the replacement motherboard next to the one you removed.
5. Unplug the ODM power cord (attached to the CPU fan) from the motherboard. Use a screwdriver to unscrew the CPU cooler from the motherboard. Lift it off and set it aside. Lift the bar holding the CPU in place. Remove the CPU and place it in the socket in the new motherboard. Lower the bar to secure the CPU. Screw the CPU cooler into place on the new motherboard and plug in the ODM power cord.
6. Remove the RAM DIMMs from their slots by pushing the tabs on the top and bottom of the memory slots. Place them in the corresponding slots in the new motherboard. Push down until the tabs lock into place. Remove any AGP or PCI-E cards from the old motherboard and plug them into their corresponding places on the new one. If your new motherboard lacks a CMOS battery, install the battery from the old one.
7. Set the old motherboard aside and place the computer case back on the table. Carefully lower the motherboard into place. Replace all the mounting screws you removed in Step 4.
8. Replace all the power and data cables removed in Step 2. Check that all connections are completely secure. Replace any components that you removed to pull the motherboard out. Screw any AGP or PCI-E cards to the case. Replace the system access panel and screw it in to the back of the case.
9. Place your computer in its usual spot and replace all power and data cords. Turn the computer on.
