This maybe a long shot, but years ago when i got a new comp a game i played would blank out and the only key on the keyboard that brought the screen back was the tab key which was used to switch to the game map. turned out the game and the power saving features on the machine did not talk to each other causing the comp to kill the monitor, unles that one key was pressed. i don't run many games these days so wouldn't know if that is still an issue.
