My computer has started getting a black screen that flashes on for just an instant. The computer is still running perfectly fine otherwise, including audio from programs.

It only happens after several minutes, if it happens at all. I'm writing this on my PC right now. If I turn my computer off for a while, the program goes away but comes back.

I suspect it may be a dying PSU.

Windows 10, Radeon R-series CPU, Nvidia 1070.... can't remember the rest.

Could also be your monitor, OP. When I use my 29" TV as a monitor, it does that flicker whenever either a) someone turned on the light switch in my room, it's usually off, or b) someone turned the control knob of the ceiling fan in the other room. I know for a fact that my house electricity is a bit funky, though. No issues with the other TV in the living room or the home server monitor.

I hadn't considered that. You might be right. If it was a PSU issue, you'd think the computer would just shut off. I think I'll buy a UPS and hook my PC and monitor to it just to be safe.

Although, that doesn't quite explain why shutting down my PC for a while temporarily fixes the issue.
