Computer shutting down on high demand Games

[KingAnachronist]

So my computer has had a few problems the past few weeks but I believe I've narrowed down the requirements to cause said shutdowns.

Basically whenever I play a high end game (most recent example being Alien Isolation.) or any game that causes an odd whirring sound from my computer (guessing it's my GPU) after a good 10-20 minutes my computer competely shuts down, restarts then doesn't boot to anything. No bios, no windows, not even a signal to my screen.

I've found unplugging my computer and leaving it for a day or so seems to fix the booting error. Checking the event viewer gives me nothing however but my computer will run fine from there. I've played much less demanding games that cause no whirring for a good hour or so without any shutdowns, problem being I can't touch any of my high end games now, a problem that didn't use to exist.

When my computer refuses to boot, removing everything but my mobo still proves to do nothing. It's hard to tell if it's a bad mobo or other parts causing the issue.

Any help would be greatly appreciated as I'd like to get back to playing my games without fear of shutdowns and being unable to use my computer, many thanks!

Overheating ! Improve the airflow .Enable the Normal clocking profile in BIOS , if possible

Open the case and see whether cables touch the fans .

This horribly looks like overheating
Check if your computer's internals are clean and if there's enough airflow, especially for CPU and GPU fans and heatsinks.

If cables are attached on a "first come, first serve" base, meaning they're just connected and left hanging in the middle of your case, order and manage them to leave as most empty space as possible amongst all the available fans.

Cable management is generally good I'd say and I have a lot of fans in the case. I have fan control for my GPU set to auto but have never heard them go off that much, is it quite likely it's the GPU overheating then?

Yeah, could pretty much be it, but it could also be the CPU that's overheating. You can try downloading softwares like GPU-Z and CoreTemp to make sure of that without opening the case, but giving it a cleanup never hurts anyway.
