Just fired up the xbox to play gears for a bit, and this happens. It's happened 3 times, haven't tried another game yet. Shouldn't be the games though since the disc is perfect. No red lights, just a frozen screen and a little static through the surround sound. If I just sit in the dashboard nothing appears to happen either...I've got a warranty at EB that expires next week, so I was about to trade it in anyway. Not a big deal, just haven't seen this particular issue posted before.
