Before I get into this very hairy issue, specs are as listed:
Mobo: Gigabyte B85M-D3H
PSU: Corsair RM750x
CPU: i5 4690k, Hyper 212 evo cooler, base clock
GPU: GTX 750 ti
RAM: 2 8GB sticks that work according to memtest
Case: outdated case that has 80mm fans
Now to the issue.
As the title says, my PC turns on and boots into my OS (windows 10 normally, I've been using Ubuntu recently as it works better from a live USB), yet after that, at seemingly random intervals, it turns off.
Some things I got through weeks of testing:
I was lucky enough to just catch some temps before it shut off, and my CPU hadnt gone above 50c, yet that's the only number I really caught.
My PSU shouldn't be the issue. It's new because my old PSU was what I thought to be this issue, it was an Orion HP400DB. (Could the crappy PSU broken anything?)
It isn't a bad OS install. I can run Ubuntu live USB fine, however actually installed Ubuntu doesn't work as well.
Overheating is unlikely, I recently pointed a desk fan at my open PC to test this.
Running with/without GPU has no effect
Despite a room temp system, turn offs are random. Could be right into Windows boot, could be hours after.
The most recent things I remember doing on my PC while it worked was around Battlefield 1's release, which rendered into me updating my Graphics driver.
I hope you guys can help me. My electric engineer brother and several others with experience have tried, to no avail.
