Problem description: I built a new computer a few months ago. Everything worked fine for a few months but suddenly my computer has started randomly shutting off on me. Specifically, what happens is that I'll be in the middle of a video game, and everything will be fine until suddenly and without warning the screen goes black and a few seconds later my computer shuts off. When this happens, I have to let the computer cool off for a few minutes before opening anything after it auto-restarts, or else it auto-shutdowns again. Attempted fixes:I'm not sure how to isolate the problem. I thought it was power, because it only happens when I play video games. But it's not any game in particular, and not consistently. Furthermore, the way that it can quickly shutdown after a reboot suggests (to my amateaur eye) that it's not strictly a power load issue. Some days I can play Witcher 3 or Elite Dangerous cranked to max for hours with no problem, but just now (after playing for about 3 hours) I shut down trying to watch a DOTA2 match. I thought it might be temperature related, but my CPU+GPU idle at ~40c and go up to ~70c under load. That shouldn't be high enough to cause a shutdown, should it? Recent changes: None -- Operating system:Windows 8.1 Pro, 64 Bit System specs: CPU: intel i5-4590 MOBO: ASRock H97M PRO GPU: NVIDIA GTX 970 Memory: 16GB DDR3 PSU: Corsair CS450M HD: 1TB HD Samsung, 1TB HD Western Digital Blue, 1 250GB SSD, Crucial M500 Location: USA I have Googled and read the FAQ: Yes/No The motherboard is an ASRock H97M PRO4, if that makes any difference.

We need the full specs, so please read the sticky and reformat the post, thanks.

That sounds like a power issue to me. A 450W power supply is very under-sized for that system, and lower-end modular power supplies have a lot of corners cut (in order to hit the same price point as non-modular units).

Is there any way to test that? Not that I don't believe you, but a new PSU is probably pushing the limits of my budget these days :s Also, if I do get a new PSU, what should I get? Or rather: how much power do I need?

I really wish I had some way to test this because on the one hand the pattern of shutdowns feels like power failure, but the way that I need to turn off the entire computer and let it cool down (otherwise it goes into a whole cylce of auto-reboots because it hasn't cooled off enough yet) feels like a temperature problem. If it was a straightforward power overload the system should be perfectly fine because after one reboot, because the problem (high GPU/CPU demand from video games) would've gone away, right? Alternately, maybe I have a fan failure in the PSU?

A PSU can fail in a variety of ways. It could work intermittently and sporadically irrespective of high power demand. Jinnigan posted:Alternately, maybe I have a fan failure in the PSU? Not likely.
