PC sometimes does not turn on

[adthelad]

Hi, strange problem i cant get my head around.

Most of the time when powering up the pc it starts fine and is stable as a rock, i've run all kinds of stress tests on the system and they run fine.

However, sometimes when I press the power button absolutely nothing will happen. I have a power button on the motherboard and have pressed that also to rule out a faulty power button. This is beyond me, anyone have any ideas?

What PSU and such do you have?

Does it do so if you only just turned it on at the mains? Had this problem where I'd keep on pressing Power button and would eventually Fire for a while. PSU (corsair ax850) was at fault and was swapped out
