Seems like there's no reason for it to turn off by itself. 3.7Ghz OC has been OC'd for more than 3 weeks with absolutely no problem. CPU temps normal. Only thing i can think of is the PSU, and also that i recently removed my GPU (GTX 1050Ti), using my iGPU now, waiting for my new GPU.

Sometimes it turns off the screen for a few seconds, and then it comes back up. My USB LEDs also die when the screen turns off (razer mamba, etc.)

PSU is a case-included 450W Voltron 225x, soon to be upgraded to Antec VP600
