I have a custom built PC that starting acting up recently. When I press the power button I get a fan spin and lights on the mobo lights up and then nothing. The fans stop but the led on the mobo remain on. I've narrowed it down to the power supply or the processor meaning that I've eliminated everything else. Could the processor be causing my problem? Any other ideas would be helpful.

Location: Sittin' downtown at the railway station, one toke over the line.
If you think it's the PSU or CPU try swapping in a known good PSU. (An old one of yours, a friend's, one from a store with a liberal return policy, etc.)

Power supply. CPU's fail like 0.0000001% of the time and in fact is the very last thing you should replace.

Agreed. The PSU is the more suspect of the two. Try switching it with a known good PSU or using a PSU tester to verify this. Just for good measure, you might want to see if reseating the CPU helps to solve your issue.

On that note, if you do that, look at the socket on the motherboard and the pads on the CPU. If you have bent pins or burnt pads, you're hosed.
