Well, mine got kaput 2 weeks ago, do some research on the net on how to fixed it and tried almost everything but failed. However, today, I decided to open up my box and stripped it to the bone. Still don't know what to do, feeling a little bit frustrated I bang the heatsink a few time with the screwdriver and put my fan on the 3rd gear with the DVD Rom out of the box (still connected) and tried to play GOW (finger crossed). AND IT WORKS..it is a miracle...after two of  my fingers bleeding (kena heatsink..be very carefull..tajam)..lastly it is good as new. But dare not to ruin it again, I decided not to put it back together. I wish I have a camera so I can show all of you how the 360 look like after I open it up...(anyway, as long as it can play games I am happy with it)
