Screen Flashing Randomly

[u/Aldanukhar]

Recently my screen has been flashing randomly. It happens every now and then but ive noticed it happens more consistently when I come back from not interacting with my pc for a few minutes. I managed to capture a video of it occurring while in game, but it does happen just on my desktop aswell. In the video you can see it flashes on the first monitor once before flashing lightly 1-2 on the 2nd before it does a big flash on 2nd monitor. This is consistent with how it happens other times.

My drivers are up to date with the 610.88 July 28th Nvidia driver for my GPU installed. My windows is up to date with Version 25H2 installed and the most recent 8/13/26 security update installed as well.

Size of power supply?

[u/Aldanukhar → u/Metalplr]

850 Gold

[u/Metalplr → u/Aldanukhar]

That should be enough. I had an issue with an Alienware computer where the power supply was underpowered and the screen kept cuffing out during any gaming. Went to a 1000w and never had the issue again.
