Comment (by umccullough):

 I'm not sure I've seen an overheating GPU cause a machine to shut down -
 usually you just get visual artifacts, and occasionally a hardware hang.

 Thermal shutdown is usually a CPU feature, however, and depending on the
 CPU model, the thermal shutdown temp may vary - I've seen some set at 75C,
 while many of intels shutdown at 90C (I've had this happen, btw... when I
 disabled the thermal protection in the BIOS on a machine that didn't have
 the heatsink/fan properly seated on the CPU).

 I would guess it could also happen if the northbridge chipset overheats -
 or maybe your laptop has some additional thermal protection built in that
 cuts power when it hits some specific case temp.

 I don't suppose you have any way of tracking the various CPU/motherboard,
 etc. temps when you're approaching a shutdown event? Can you duplicate the
 behavior on say Linux with a heavy load applied to the machine?
