Computer Turning Itself Off, trying reboot failing

[mrwaffles]

Hey guys I'm running a 750W Silencer PSU on an MSI P67A-G43 (B3) motherboard. I haven't had any problems until this week. My machine randomly turns itself out, no error message nothing, then tries to power back on failing after 3 seconds. If I turn the PSU power off, wait a few seconds, turn it back on a reboot the computer it works fine. This has happened twice this week. Is my PSU on it's way out? I've had it for about 2 or 3 years now. Should I be ready to replace it? I swapped the power cable, and changed ports on the power strip.

What is your PSU exactly? Silencer? From PCP&C?

or not?

Are you sure it's not an overheating? Check all temps first...
Try reassemble all cables and make sure all components are free from dust..

I think that one is mine. I bought it awhile ago and mine is bright red. The machine isn't over heating, at least according to HWMonitor. The fan on the PSU is spinning and everything is pretty dust free.

What you’re explaining is indicative of a bad power supply. When your pc powers off does your psu feel overly hot?

So I managed to fix this problem by unplugging the reset switch from the motherboard. There must have been a short, or something. Who knows. Oh well I haven't had a problem since.
