Windows 10: My monitor screens will flicker when I play some games, then all ports will stop working!

So I’ve been having this issue with my pc, where it’ll turn on and run just fine, but when I try to play some games like overwatch or Valorant, the screen will flicker a bit before going dark. My mouse, keyboard and any other connected devices stop working as well, though I know that they are still getting power through the pc, because certain devices, like my speakers or a midi controller’s lights will still work. My pc also never actually turns off. All of the LEDs on the GPU and the RAM stay on inside the pc, it just seems like all of the ports connected to the motherboard stop working. Aft

Screen flickering while gaming

Hello,

My problem is that basically anytime I launch any game the screen with start flickering nonstop. It will work normal for a few seconds, than it will go black, come back for a few seconds in awhile then do the same thing over and over again. The game is running
in background without issue during this time. If I alt+tab from the game to desktop the flickering stops, once I go back into the game it will show me the game for a few seconds and start flickering again. For the games that allow to switch to windowed mode
by pressing alt+enter the flickering stops and I am able to play the game normally except from the inconvenience of having it in windowed mode.

I have a dual monitor setup and I read online that it is a common issue with windows for such setups but none of the suggestions I read there helped me to solve it. By the way, while the game if flickering on main display, the secondary monitor is running
mostly fine and will only flicker occasionally. I had the same issue in the past, when after a windows update the flickering started, the way I was able to solve it back then was to uninstall the update and stop windows from updating again. A month ago I had
to reinstall the windows and everything was working fine until I got this big October update installed. This time around I am not given an option to uninstall the update so I am stuck with the flickering problem...

Any suggestions?

Thanks

Screen flickering while gaming

Hi Lane,



Thank you for writing to Microsoft Community Forums.



What is the make and model of the computer?

Is this issue specific to a particular game?

When was the last time your computer worked without this issue?



The problem could be caused by the GPU or cables.



I suggest you to try with the steps mentioned in the article below.

Troubleshoot screen flickering in Windows 10.



If the above steps do not help, try with decreasing the monitor refresh rate.

Go to Settings->System->Display->Advanced display settings->Display adaptor properties for Display 1->Monitor->Screen refresh rate.

Click on Apply and then Ok.



Hope it helps.
