To start off my xbox 360 started last month turning itself off and changing the screen resolution and after the recent Beta update the console is now turning itself on and off by itself.
The console is a 250gb Xbox 360 Slim and I am using the Hd component cables, I have tried to use a hdmi cable and it still does the same thing.
Does it turn on right after you turn the Xbox off, or just randomly during the night? I was thinking that the guide on your Xbox 360 controller might have been getting stuck, or the power button the Xbox 360 has been getting stuck or something, but that probably isn't it. Might be worth calling Microsoft, see what they say.
If you're worried about it wasting electricity, go to your guide and go over to console settings. In the system settings you should be able to set an auto shutoff time.
