So I've had my PC for a couple years now but in the past 2-3 months (maybe longer, I can't remember, but definitely past 2-3 months), it's had this nasty habit of literally just turning itself off.
I could be playing a game, watching YouTube, browsing, or even just idle on the desktop with nothing running (apart from background processes). It'll shut off. It doesn't discriminate.
It doesn't happen all the time though. Sometimes it won't do it, sometimes it'll do it 2 or 3 times in a row (about 20 minutes in between shut downs). But after a few shut downs, it'll sort itself out and won't turn off on its own again.
So I thought initially that it might be something wrong with my OS, or a virus or so. I've just reformatted. But as I was transferring my files back to my main drive, boom, it did it again.
I've pulled my computer tower away from any blockages (it is under my desk, but it has about 2" at least on each side for air flow). But that hasn't helped anything.
I'm now coming to the conclusion that it's either PSU related (maybe the PSU is faulty and not supplying a steady voltage?) or it's heat related.
I don't have any software to monitor those readings though.
It's worth adding that when I reformatted, I made an internal partition using Win 8.1s disk management system, which I put my backups on. I then reformatted C: and reinstalled 8.1 there. I then copied my backups off of my temp partition and then expanded C: back to its full size.
Any help would be greatly appreciated. I think I've mentioned everything I think is relevant.

This was a prebuilt purchase from a website so they did the compatibility checks etc. I've never had an issue with it until now.
