Suggestion:
Let me be the first to say that I know how you feel about your xbox 360. I had the ring of death happen to me a few weeks ago and the support that I got from microsoft was horrible! A few of my friends didn't have a problem with them though.
So I did some online research and I found this cool site.
http://www.ultimate-gamers-community.com/userguide-fixing-xbox360
It had a few helpful tips to help me fix my 360 from the ring of death. It may seem a little complicated at first but if you have music to movitate you then it really helps. And some coffee.. hahaha.
If you want to contact microsoft then here's the number: Call 1-800-4MY-XBOX
I hope you get your xbox 360 fixed soon. I hate the ring of death and I hope it doesn't happen to you again!
