For some reason, whenever i'm trying to do something, at some point. My computer screen will restart itself and everything closes. It doesn't restart completely, the screen just goes black, and i'm back at desktop mode with everything closing. It's starting to get super annoying, especially when i'm trying to do some work or even playing some of my games, and all of a sudden, everything closes and i have to start all over again. Even when i don't have lots of tabs open, it still does it. Is there some way of fixing it? If so, pls let me know and thank you
