How to Install a New Processor

The CPU (Central Processing Unit) is used for calculating values or moving registry entries. The GPU (Graphics Processing Unit) is used for similar functions.

1Find out what type motherboard you have; different motherboards have different sockets. Make sure your CPU is accepted by your motherboard, power supply, and cooling components. A list of common socket types appears at the end of this page.

2Open the case of your computer. This is usually accomplished by a latch, button, or other release mechanism. If necessary, refer to technical manuals to find out how to gain access to internal components. Depending on the type and model of your computer, a screwdriver may be needed to open the case.

4Remove the heat sink. This is usually an aluminum block with fins to dissipate heat. Attached to the heat sink will usually be a fan. Unplug the fan from the motherboard. Also remove any clips that attach the heat sink to the case or motherboard. The CPU should now be exposed.

5Lift the latch on the side of the socket which will slightly raise the CPU, then remove it.

11Reassemble or close the computer case. Make sure all internal cables are attached to their original locations.

Tips
Make sure all cables go into their original ports; just because it fits, it does not mean it goes there.
Some good CPUs to upgrade to: Core 2 Duo, Pentium D, and Core 2 Quad. Stay away from these processors: Pentium, Celeron, and the Atom. If you really want cutting edge power, and are not worried about paying a premium price go with the Core i7 or the Core i7 extreme. Be careful though because some motherboards do not support the new Core i7 socket configuration. Core 2 Quad Extreme is a good choice if your if your motherboard can't support the new Core i7.
If a component or cable does not fit in the slot you think it goes in, make sure before jamming it in and possibly damaging it.

Warnings
Be careful with that little piece of silicon: it’s delicate and expensive, with some worth over $1,000.
Always ground yourself before reaching into the case, each time. You can do this by touching a metal table or chair leg, or even the computer case, if it is metal. Any static discharge may fry sensitive electronic components.
