The Installation Well, first, there is the obvious. Make sure you are buying a CPU that your motherboard can support. If it doesn't, buy a new motherboard. Get a CPU fan rated to cool the processor. Most retail CPUs come with a fan, while OEMs do not.
Lets proceed with the upgrade.
Locate the processor on your board. Check to see what type of socket or slot it is using. A socketed chip will be sitting snuggly in a socket, described above. If your chip is socketed, look and see if you have a OverDrive socket somewhere else on the board. If this system is a more modern one, there will be no OverDrive socket.
