CPUs each have different architectures supported by only certain motherboards.
Your motherboard only supports one type of socket, generally providing you with only one range of processors to choose from when you want to upgrade. If your motherboard doesn't support a particular CPU, don't try upgrading it with that component, as you might damage the entire system. Your motherboard usually has the CPU socket number written on the bottom of the socket to ensure you do not mistakenly assume it has another one and upgrade with the wrong type of CPU.
Instructions
1. Disconnect all cables from your computer and turn the computer with the rear facing you.
2. Remove the screws holding the right-side cover to the computer and lift off the cover to expose the interior. If you don't have screws, look for a small plastic tab on the computer that you push to release the cover.
3. Look around your motherboard's CPU for a socket number. This number represents the types of CPUs you can use. Some common socket numbers include "LGA 1156," "775," "LGA 1136," "Socket A," "AM2" and "AM3."
