Weird problems with windows 11?

[Apollyon_the_Destroyer]

My computer randomly restarts for no apparent reason.

Also, my screen occasionally flickers on and off.

I don't know why but the flickering stops when I run a defender virus scan?

I have updated firmware and video, wireless, and bluetooth drivers but both problems still persist.

These things never happened with windows 10.

Are these windows 11 problems?

"Try to upgrade graphic drivers to latest from vendor Site, if it's still facing same issue roll back to previous version."

Newest driver and rolled back driver didn't solve problem.

It was not a problem in windows 10 until after I rolled back to 10 from 11. Why?

go to device manager and uninstall Present Graphic driver , and the its roll back to Microsoft Basic adapter and check now wheather your are facing any flickering issue or not .
