My gaming pc randomly turns off from time to time.

I could be gaming, mostly playing WoW or LoL, or sometimes just watching Youtube.

But my computer seems to turn off, and every time i have to unplug the cord from the back of my power supply and turn it off for about 15-20 minutes, plug it back in and it works.

Any ideas what could be wrong with it? my warranty has run out, so I'm wondering if I just have to replace the power supply, or if it could be something else.

Something is overheating in a major way at a guess. Have you made sure there is minimal dust in the PSU, etc?

Overheating? Check if fan is connected and heatsink in seated properly.

Event viewer might give some clues incase of faulty ram.

See if the temps are in range. Other than that, a cheap power supply for testing is cheap.

Obviously a thermal issue somewhere.

Have you overclocked your CPU or video card?

I've heard of video driver updates causing shutdown/reboot issues usually where the power supply was not powerful enough to begin with.

As mentioned it could be a failing power supply. If your machine is out of warranty (assume its 1 year) the individual parts may be covered by longer warranties. Most PSU's from good manufacturers, like Corsair, may cover their stuff for 3-5 years.

+1 for overheating or PSU, although if the PSU is not a good brand I'd actually put that ahead of overheating as an issue.

The number of "gaming" rigs I've seen provided with 400w hung flung dung PSU's instead of a nice 600W Seasonic or something.

Check your BIOS settings for an option to have it beep when the temperature gets over a specific range. That may at least let you know its about to happen.

Tho if its your graphics card overheating rather than something on the mainboard, the temperature warnings may no apply to that.

Thanks guys, i think this may be a little too complicated for me to fix on my own, think I'll just take it back in to where I purchased it and see if they can fix it for me.

The problem usually lasts for a week or two, turning off at random times, and then sometimes it doesn't happen for months.

I have opened my pc up, nothing seems hot, and it has barely any dust.

Although today when it turned off, and when I turned it back on, my keyboard, mouse and monitor weren't responding (for the first time ever) so I opened up the pc and unplugged/plugged everything back in, it seems to be working again now, but I'll just see how it goes, and try some of the thing's I've been suggested.

Thanks

Also no I haven't overclocked my CPU or video card.

Run something like CoreTemp to monitor CPU temps, if temps arent getting too high (if you can see them before it dies on you), then suspect the PSU as others have mentioned.

Downloaded Coretemp, have supplied a picture of how my pc looks at the moment, what temp should I expect my PSU to be running at?

If you are having to leave it powered off that long to come back then it almost certainly is the powersupply going into protection. If it is a multi rail power supply with detachable cables then check you do not have everything plugged into one of the 12v rails and nothing on the others. I saw that on one PC because the builder thought it was neater with all the plugs in a row.

Otherwise it might just be a piece of crap power supply.
