You're not alone. Apparently Brian of Kotaku has had a whole bunch of 360's break on him. His latest one was a 360 Elite that looks like it suffered from a DVD drive malfunction.

"Over the weekend we had a little neighborhood party at my house and in the midst of it I decided to show off Guitar Hero II for the Xbox 360. We played it for a bit, maybe 30 minutes and then I went to turn the 360 off and turn the music back on. When I pressed the power button on my Xbox 360 Elite it started making sounds like a blender. This lasted about 10 seconds and then it powered off. I found the news a little bizarre, but didn't think anything of it until Sunday night."
"Then I hopped onto the Xbox 360 forums and discovered I had just become a member of the broken DVD player club. So that's eight dead because of a Red Ring and one dead because of a bad DVD player. Microsoft really needs to get their shit together. As I pointed out to Peter Moore back when they announced the new warranty for the 360, warranty or no, customers are still going to be annoyed if their new or relatively new consoles keep dying. It's an inconvenience and certainly shakes confidence."
