My laptop is having an issue. whenever I go to play a game (browser games not included) I have an issue where the pixels on the screen flicker so badly that i can make out anything on the game. this does not happen with pictures or menus in games, just the sprites and enviroment, issue started last night. have rolled back drivers, system restored to a point from before the issue happened, restarted computer, and reinstalled game. none of this has solved the issue, Please help.
