I just can't imagine it being the PSU because it works fine all day with any interruptions. The computer doesn't fully turn off, it just sometimes basically restarts. It seems to happen when my PS4 controller isn't plugged in. I've had issues with my PS4 controller causing my computer not to boot past BIOS. Weird.... I guess I could try swapping the PSU.

Is there a way I can test that this is the issue instead of just assuming it?

I don't understand how it could be the PSU when it only happens once? It happens when I turn on the PC for the first time of the day, and it never does it again?

Intel Core i7-6800K NVIDIA GeForce GTX 1070 MSI X99A Godlike Gaming Carbon Kingston (HyperX) 32GB DDR4 Microsoft Windows 10 Home EVGA Supernova 1000G2 It's never done this before...

All the fans are spinning, temps look fine under 40°C. I'm speculating it's my PS4 controller plugged in? I've had issues when booting up the computer, and the PS4 controller doesn't let it boot past the BIOS screen until I unplug it.

I have this issue where I boot up the computer like normal, and everything is fine. Then randomly, my monitor goes to no signal, keyboard turns off, and my mouse stays lit. It turn's back on after a minute or two. This is completely random, and I have no idea why its doing this. If you need any info or specs let me know. OS: Windows 10 64 bit Home Thanks.
