Not really all to sure why it is doing this but anytime I go to play a game I can through the menus and everything but as soon as I start to play my xbox just shuts itself off. Even my controller is left hanging like it's blinking for the connection that was just there. I've tried unplugging it and doing a hard reboot but so far nothing is working. I thought maybe at first it was just disc games but I just tried geometry wars and got about 2 secs of movement and it shut down on me which is way more than what I can get out of Gears now. Please help me!
