Question Monitor and peripherals shut off but PC is still running?

Dec 21, 2020
Hey all
So this has happened once before pretty recently id say a week ago. I was playing cyberpunk and my monitor and all peripherals shut off, but the PC and is still running, rgb still on fans spinning etc. I read that it is likely a psu issue so I made sure everything is connected which it is.

I turned off a Windows power setting (or turned something to gaming mode idk) recently too and it only started happening after that. I've had this pc for probably a year and a half.
The last time this happened I just turned off the power supply for a few minutes and came back and it worked just fine until today when it happened again.
Oh and when I turn it back on now the pc starts up but still nothing else.

I have a 650w psu
GTX 1080, ryzen 7 2700x

Any help would be greatly appreciated, I really do not want to buy and new parts.
