okay ive got an ongoing issue thats driving me insane, for random reasons my screen goes black, not no power black just black. pc continues to run it doesn't lock up. sounds continue, videos, games, i can use windows key right arrowx2 and down arrow x4 to restart the laptop each time. intel i7, nvidia 675m, have reinstalled windows 7 twice, used ccleaner to remove all old drivers and installed eveything fresh.
the odd part is the complete randomness of it, sometimes you can surf web, game, anything for hours with no problems. then at other times i have to start and restart 4-5 times in 15 min. i'm at my wits end, just about ready to dump a 2y/o laptop.
