I have a really annoying problem that I can not for the life of me find a solution to. So two days ago my windows got a malware/virus which caused chaos so I ended up eventually refreshing my windows. Time to time the windows flicker which is fine but when I play games, it flickers heavily and makes it unplayable. Right now I have tested League of Legends and Hearthstone, both of which windows flicker. I also ended up reseting my windows 10 the second time but the problem persists. I'm sorry if I'm not being clear but I did make a video last night to visualize my problem:
Any help will be appreciated, I just wanna know the cause of this and what can I do to make it go away. At this point I think I might have to do a fresh reinstall. Thank you.
