My xbox 360 randomly turns off, with no indication of over heating or anything. the whole system shuts down. it is also instant shut down not like slow shut down. the power brick is orange, but when the xbox turns on it turns green. the xbox will turn on and start to run. when get into any game and start to play it turns off. the only thing i can think of i i have a lot of electronics plugged into a strip all at the same time. that is when the first time it happened, so i moved the plug directly into the wall. it still happens. this is an xbox that was just working fine 1 day ago. all of a sudden it does this. i have no warranty. what does anyone think it could be?
