To restart your graphics drivers, press Win+Ctrl+Shift+B on your keyboard.
Your screen will go black for a split second and you’ll hear a beep. Everything will then reappear just as it was before you pressed the hotkey. All your current applications remain open, and you won’t lose any work.
We even tried this shortcut while playing a PC game. The game kept running properly after we used the shortcut. That’s because Windows just restarts the graphics subsystem. All your applications are left alone and will continue running normally.
