Or your graphics driver crashes in the middle of a game, and your screen goes black for a few seconds before recovering. Or your audio driver just gives up, and you have to reboot to get sound back. It's always a mystery which driver will betray you next. And hunting down the right driver version on the manufacturer's website is like navigating a maze.
