It might be a dumb question, but then again I'm not a PC mastermind. You see I've been playing a game these past few days and every now and then the game freezes the entire PC. That means no alt+F4, no task manager, nothing, it just sits there until you restart the whole PC. 3 times this happens and all 3 times I've saved an hour before the freeze. Now this only happens while said thing is fullscreen, not windowed or borderless, why is that? Can you guys enlighten me?
