I just got my xbox 360 elite about 5 or 6 months ago. About two days ago I turned my xbox 360 elite after about 3 months of turning it on. Everything was fine. And two days ago I also downloaded the new update where you get avatars and everything. So just yesterday I turned it on and i was on the dashboard and it froze so I turned the console off and I turned it back and it kept on freezing. I did this about 3 more times and about the fourth time this e71 error came up on the screen after I got the 3 ring of death and I also got the 4 ring of death. Just today I have turned it on and it keeps on freezing but the e71 error report hasnt popped up on the screen and none of the rings have turned red. but it is still freezing. There was a lot of dust on it before the error occured and I just wiped it off with my hand.
What do I do to fix this problem?
