Spent all day trying to get my PC working, it would boot and turn itself off instantly, not even making a beep so I thought the worst, either cpu, mobo or psu being knackered. Had the whole down to bare minimum parts, even took the heatsink off the cpu and put it back on.
Turned out to be the power button going on and off by itself!!!
Gah!!! *FACEPALM*
