Ways To Fix Monitor Randomly Goes Black And Comes Back On Issue

1. Loose power cable

At times, the main cable connecting the moitor to power may have become loose or the switch itself might become faulty.

This causes the power supply to constantly go on and off, thus resulting in the closing of your monitor i.e. blackening of the screen and when the power comes back, the screen turns on.

If your monitor runs on higher refresh rates, then always prefer to use high quality of cables to connect it.

So, uninstall and such software and reverse the overclocking.
