When I play games and I Alt+Tab or try to change the volume from my keyboard's hotkey, the screen turns black, flashes couple of times and I get the message from the picture below(Display driver failed to start). Windows then sets the display driver to default, so it switches to integrated video card. I was given this message in the Device Manager:
"Windows has stopped this device because it has reported problems. (Code 43)" I have the latest driver installed.
