This is somewhat Mac related, but I think it's more of a chip issue (esp on factory-assembled boards), so I figured I'd post here. Basically, I'm having repeated failures of an ATI 4850 graphics card ...
Solder connections on processors seem to be a very common failure point in modern electronics. Consider the Red Ring of Death (RRoD) on Xbox 360 or the Yellow Light of Death (YLoD) on PlayStation 3.
