My box is running 5.2B right now and it has been working fine for the last 5 months. Now today though when im running games, they are freezing 1-3 min after I start. I have tried both a burned gears of war and the original pressed halo 2 and they are both freezing. I dont think it is the dvd laser or over heating since it is 1-3 min after starting play. After the in game freeze if i power down and start up again, it freezes at the beginning of the xbox logo screen. I have to let it sit for a good 5 min before it will turn on again. Please advise! Any help is greatly appreciated!
