About three days ago i was playing smackdown and it froze on me. It gave me a scrambled screen. I thought it was the game because it had a few scratches on it so i took it to get it resurfaced. Well today i was playing Oblivion and it did the same thing about 3 times in a row. So i put in Gears of War and it did it at the main menu screen. Then i turned it off and turned it back on and it froze at the xbox 360 screen. And to add to the trauma i bought it from gamestop with NO warranty. I've only had it since april 2007 too. So i have no idea what to do with it.
