Contact Microsoft tech support first. GameStop won't take it back if you've had it since '07. I could clearly tell that's what I had when it happened to mine. I sent mine in for repair. Turnaround time was fairly quick.
thanks.
thing is i got off ebay. i think i still have the paperwork, but i think it was one of those refurbished ones. but again it's worked golden for years. hope microsoft would still be down
it started last night (probably played for an hour and a half, switched out games, then 15 minutes later it shut down). really i can't even tell if it's a red light. but when it does shut off, there is a light that blinks (even if it's off).
i've heard there is a hot towel method. or that i could just try and not using it for a day or two (i waited 24 hours before turning it on, still happened).
