A central processing unit, called a CPU for short, is a small microchip that can be thought of as the brain of a PC. The processor carries out millions of calculations, enabling a computer to run the operating system and processes its users require. As such, upgrading to a faster CPU is a common way to increase overall computing speed, although oftentimes upgrading other components, such as RAM, is a more cost-efficient way to improve performance.
Instructions
1. Open the computer's case with a Phillips screwdriver.
2. Find and remove the CPU fan and heatsink. A large fan should be attached to the motherboard, on top of a metal heatsink. The fan and heatsink will either need to be unscrewed, or a clamping mechanism will need to be opened.
3. Unclamp and remove the old CPU. When the heatsink is removed, the CPU will be visible in a plastic or metal housing. To get the CPU out, pull up on a locking lever to release the CPU, then gently grip it on either side and pull it out.
4. Put in the new CPU. In the open CPU housing, place the new CPU the same way the old one was situated. Push down on the locking lever to clamp the new CPU in tight.
5. Apply a thermal transfer material to the heatsink or processor, so that there is no air between the CPU and heatsink.
6. Reattach the heatsink and fan, and close the case.
