Windows 10: Black box appearing on screen randomly.

There is a black box randomly appearing on my screen out nowhere and when it shows up almost everything stops working for a few minutes, it stays there and my only way of making it disappear is restarting my computer, but it still shows up. I took a screen shot of it and when I went on windows defender it said this, I'm on Windows 11 by the way.

Computer randomly has black screen and restarts

Taco this could be software also. Before you get all crazy, do as Erocker suggested. Find out the error in the Event Viewer. Look for the faulting module and the error code itself. Also check the reliability monitor. At the bottom it will have "View all Error Reports". Post a screen of whats in there if anything.

This could be a simple as a bad driver install.

ALSO have you downloaded or installed anything lately? STAY OUT OF THE DAMN BIOS UNTIL WE KNOW THE ERROR! lol. I know you. Baby steps boy, baby steps.
