JUST in case you are interested to know - (as I am not any sort of grammar nazi)

CPU stands for Central Processing Unit.  That's actually just something inside the PC, the processor.  
PC is probably the acronym you are looking for which stands for Personal Computer.

When I first saw the thread and so many replies I thought, woot a thread to show me how to overclock my processor = D ie get my cpu up.
