|If you don't have the knowledge (or the effort) to actually find out your CPU model beforehand, I highly doubt you'll be capable of replacing the CPU in the first place without external help. It takes finesse and knowhow to successfully replace a CPU without FUBAR'ing the pins or thermal paste job. It ain't hard, but there sure is one heck of a lot that's there to screw up.|
Like above posters said, there's lots of different sockets. You could try CPU-Z as it keeps a lot of info right up front, iff you're still pursuing this.
