I have a PC that I built myself (parts list). It has for a number of months refused to turn back on after there's a power failure. I've had to pull the plug out of the back, and then plug it back in and hit the power button to get it going again. After the most recent power failure, even pulling the plug didn't have any effect. Pushing the power button results in no action (that I can see) taking place (no fans, etc).

Any ideas of what might be the problem? Is there a good way to systematically determine which component has failed?

Is it plugged straight into the wall or a surge protector, and have you checked your breaker panel? –  ekaj Jul 16 '13 at 0:51
It's plugged into a surge protector, and there are other components plugged into that same surge protector which are working fine. –  bdukes Jul 16 '13 at 1:48
Does a light come on, on the motherboard? –  cybernard Jul 16 '13 at 5:09
If pressing the power button does not start the computer its likely one of two things. The first suspect is the power supply the second is case. –  Ramhound Jul 16 '13 at 11:37
