Things You'll Need:
- Owner's manual for computer
- New processor
- External storage media
- Thermal compound
-
Step 1
Find out if it's possible to install a new processor in your computer. Most computers allow for processor upgrades, but some have CPUs that are integrated into the main board. Refer to your owner's manual to determine what kind of processor your computer has.
-
Step 2
Buy a new processor from a computer parts dealer or at an online auction. Refer to your owner's manual to determine the fastest CPU your computer can handle. For example, it may be something like a Pentium M 1.8 GHZ on 400 FSB.
-
Step 3
Back up your data on an external hard drive or another medium. Usually the contents of a hard drive remain safe when installing a processor, but things can still go wrong.
-
Step 4
Remove any metal rings, watches or bracelets you're wearing.
-
Step 1
Unplug the computer, open the case and touch something metal to eliminate any static charge.
-
Step 2
Unplug the heat sink and fan. Unlatch the mechanism that holds the heat sink in place, then remove it from the computer. Lift out and up on the side bar that holds the original processor in place, then remove it. Refer to your owner's manual if necessary.
-
Step 3
Install the new processor, making sure it is securely attached and properly aligned in the CPU housing. Apply a thin layer of thermal compound on the CPU, then replace the heat sink and fan. Secure the retaining mechanisms and plug the fan back in.
-
Step 4
Plug the computer in and restart it. Follow the instructions in your owner's manual to enter your system's BIOS (basic input/output system). The new CPU should now be recognized by the BIOS.
-
Step 5
Replace the computer cover.
