My Xbox 360 started freezing last night, it all seemed to occur after plugging in my wireless usb headset. I don't know if thats just a coincidence. It freezes when ever I load games, sometimes on the menu screen of the game and sometimes as soon as I load the game. I would say it freezes within 1 minute. Already tried 2 different games, clearing cache, removing hd completetly, checking cables, moving to different power source. Does anyone have any ideas or should I call for a coffin?
