The CPU or Central Processing Unit of a computer is one of the core things that make computers run. This is because it helps interprets the instructions and processes the data contained in the software. In short it serves as the brain that lets the computer achieve certain things such as typing on MS Word or using the Internet Explorer.

CPU’s are usually replaced because there are always newer and better ones coming out. They help speed up a computer that is growing older. It is like a plastic surgery to make one look younger for the computers. However, getting the best and latest CPU’s are not the only answer. It is only a part of the whole picture. If you have other slow component’s the full speed of the CPU will not be felt.

If you are planning to install your own CPU, first make sure that it is compatible with the motherboard. The motherboard should also support the speed of the CPU you are about to get. You may not be able to use the newer CPU if the motherboard doesn’t show the settings for the newer CPU speed.

Before buying the CPU check out the manufacturer’s website. Check for the settings of the new speed of the CPU and also the BIOS updates that support it too. Also check the speed setting of the motherboard’s BIOS for the speed of the CPU. You can do that by pressing F1 or DEL to enter the BIOS setup when the computer is being turned on.

The bus speed of the CPU should also be checked. The motherboard should support the bus speed of the CPU.

Then after all is said and done with the compatibility, turn your computer off, remove the case and lift the CPU. Be gentle about it. If your CPU’s are in a socket you will need to pull of a lever to remove it. If the CPU’s a slot, you would need to pull the edges of CPU’s bracket.

Before inserting the CPU into the slot make sure that there is a properly attached heat sink and fan.

Then change the jumpers to make it match the new CPU speed based on the manual. You may also change the settings in the BIOS speed to match the CPU’s. Restart your computer and you are ready to go.

Unlike changing or installing the hard drives or motherboards, you will not need to reinstall the operating system.
