Hi Our xbox 360 keeps turning off. In the summer holidays I accidentally clicked on Dowload transfer history and it shut down immediately. I kept meaning to ring but kept forgetting. We got it on again but it just turns off in middle of a game. My son has been trying to play minecraft this morning and it is shutting down constantly. We unplug and plug back in and it comes back on. Any ideas please thank you. We are still under warranty so can sort but just hoping it is something simple.
