I posted earlier that I'm on my 4th system since I originally purchased it in December of last year. It too now is dead. It won't boot up half the time; the other half it freezes within 30 seconds. It might've happened sooner, but I haven't had any time to play it the last few months because of school. (My copy of Gears of War I bought the day it was released is still sealed!) I called MS and after begging they agreed to send me a pre-paid shipping box (probably in large part because it's my 4th system). He also told me to call them again once I receive the new machine to purchase the warranty extension. Are they planning on sending me yet another bad machine?
