Red Ring O' Death

I decided I wanted to play a little 360 last night. Only 2.0 was online, but when I went to look at his gamer score the screen when blank. When I restarted the machine it came up with the "Red Ring of Death" I was tired and kind of pissed so I did not want to deal, so I left the research into what to do next until today. I found this site that looks helpful.
