Computer black-screening when exiting games

[Raspberry Horse]

I'm a fairly new on PC. I know the basic things you need to know, but I'm still a noob. I recently came across this problem where when I alt tab or close a game, my computer blackscreens, Ctrl+Alt+Del not working, pressing escape, or waiting for it to fix itself. I can not continue once this black screen shows up, must reboot. If I have Skype in the background it still plays and I can still talk with people, I just can't do anything. I'm running the latest drivers and windows update. I have unplugged the power supply and let it drain for about 30 minutes, still nothing. This problem is starting to get annoying. Someone plz help
