So there are two kinds of 360 on the market. There are the ones without the new heatsink. These have a tendency to...die horribly. And there are those with the new heatsink, which seem to work a lot better. Which one have you got? Ben Heck can help you, with his highly scientific methodology. First, get a camera. Then put your camera on top of an overturned 360. Then take a picture. If you can see your DVD drive, you're fresh out of luck. If you can't see it, you've got a new heatsink in there and your luck reserves are in good shape.
