I just bought an xbox last month I am in Iraq. I have it plugged into a transformer and i can watch movies and listen to music fine but after about thirty minutes of playing the xbox randomely turns off out of nowhere. It stays off for a minute or two and then it can be turned back on and then it only stays on for about another 5 to ten minutes and it consistently is doing this. I have changed plugs I have used a different transformer I even went so far as buying a new power supply. I am not understanding what is wrong with it.

Maybe you have the sleep timer on try going to the x box dashboard and look for sleep timer....maybe that will help

Jamie, it is obviously something internal. I know the 360 has heat protection circuit which it sounds to me like your system is overheating. It is a common problem unfortunately. If your system is under warranty, I would get it RMA'd. If not there are several places out there that can fix it. You could also run your 360 upright if your not already doing so and see if it makes a difference (as they say it is the best way for keeping the xbox cool).

I have used www.xbox360repair.com before when my xbox started giving me the red ring of death. Fast turn around time and great service. It also only cost me $70, I would not hesitate to use them again.
