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.
