When you hover over the yellow bang, what does it say? Is it from the system, peripherals, software...?

Probably a display driver crash.

Likely a display driver crash as stated.


I've also noticed low-quality HDMI or Displayport cables can cause screen blanking occasionally as well.

Nothing. Just yellow exclamation sign as tray icon.

How much RAM do you have? Have you done anything to change virtual memory settings?

There might be something in the event log: Right-click on the start button -> Event Viewer -> Windows Logs -> Sytem (assuming you have Win10. It's somewhere else on other versions).

8gb. No.

I think this is the error message saying "Display driver nvlddmkm stopped responding and has successfully recovered" from Event Viewer. It seems like downgrading to the older version of GPU driver is working fine currently.
