So for a couple months now, every time I log onto my laptop a black screen appears. It is labeled under windows something it happened for a while and would disappear as fast as it appeared. It didn’t affect what was going on in my computer that I could tell. But that was until today. I logged onto my email and my entire screen went black and now I can’t connect to my email. Also the apps on the bottom did a refresh type thing. Any idea what it might be. Thanks!
