Fix these issues?

[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 persist.

These things never happened with windows 10.

Are these windows 11 problems?

Thanks for the question. However, this space you've posted in, the Tech Community Ideas space, is for ideas for the Microsoft Tech Community website, not Windows 11. Please post future questions about Windows 11 in the Windows 11 discussion space, where I am moving this post to. Thank you!
