PS3 wont load or play games, Just a blank screen.....

Try playing a Demo game, if you dont have any download it from playstation network. The point is just to force the sytem to play games and if you notice, movies and games are listed under a different folder in the icon's list, so playing a demo game will force the system to play the game and you should be able to play your games fine after that,. Thing is that a game's info might've got stuck in freeze mode when the system was shut off unproperly while a game disk was still inside, that's all. Good luck, dont wanna see any PS3 comrades suffering the unspeakable horridness of not been able to play games. Be strong my friend.
