And a reboot solves it, then it's some driver issue. Try the latest from your card's maker and if not try other than sleep. Try hibernation.
My monitor flickers in different shades of black whenever I start up a game. The colours make it look like the display is turning on and off. I can alt-tab/ctrl-alt-del to kill the game but the problem persists until I restart. After I restart my computer, the games work fine and I can play for hours.
I have reinstalled my graphics drivers, then my operating system, switched monitors with a friend and ruled out overheating(since I could play for hours after a restart).
A friend of mine suggested that the only thing constant in my tests was my habit of putting my computer to sleep at night but I dont think its causing the issue since a lot of people do that right? But indeed after a night's sleep the games act up again.
Any help with my issue would be appreciated.
