Random shutdowns

[quik1991]

Hopefully someone can help me figure out what's wrong!

My PC keeps shutting down... I could be playing a game, on youtube, listening to music or just doing nothing and my PC will randomly lose power. Most of the time it loses power and switches back on straight away as if nothing happened. Sometimes it switches off and refuses to come on, so I need to open it pull out the connections and put them back in and that usually fixes it, but sometimes I just need to wait and it will randomly start working some time later. I've checked my CPU and graphics card temperatures and they're all fine so I don't think the problem is overheating, even though it does look that way.

Any ideas what it could be? I don't have access to a spare PSU to swap it over to see if that's the problem... so is there anything else it could be that I could check for in the mean time while I try to get another PSU? Thanks for any help!

If you have checked your temperatures and they seem OK it would suggest the problem may be with your PSU.

In the mean time (Until you can get another PSU), I would unplug all non-essential devices and run the PC using as little power as possible.

You could also try downloading some memtest software and running that, although I'd imagine if it was a memory problem you would get a blue screen / memory dump, then a power off.

Anyways, good luck in sorting your PC, hope I've helped...
