What is causing my 360 to do this??

I just got my box back from microsoft yesterday and it was working fine (I sent it in because there was a video problem). Today, though, I tried playing the Rage demo for the first time and once it launched the console immediately shut down. This happened one more time and I gave up. Then I started to watch netflix and got through almost an entire episode of 30 Rock and my box shut down without warning. I'm afraid its going to keep doing this and i'll have to send my box in again. What could the problem be?

What? Yea, it does matter. Can I get a helpful response from someone? Also, I dont want to have to call microsoft again. I'm sick of dealing with people I can barley understand in twenty minute phone call. Its such a pain. And google doesn't always have the answer.

Good point, they did give me a 3 month warrenty when it was sent back. What a joke, i'm going to have to wait another two weeks.

FYI, you can submit a repair ticket through the website if you don't want to call them. When my old 360 died I went through the whole process on xbox.com and never had to deal with any hold times or broken english.

What's causing it is 360 is piece of crap.

Mine is almost 1 year old and already feel like it's breaking down, fan sounds like helicopter.
