I have a problem that mostly occurs when I'm running games that has fast flickering lights like horror games in full screen mode. When the lights in the games gets too intense, black horizontal flashing lines appears on the screen. I have tried with another monitor but with no change. I have not over-clocked and the cooling is very good. I have all the latest drivers installed. I can run the games in window mode without getting the horizontal lines.
Do someone know a fix or what's causing this in full screen mode only?
