You sound as if your problem is similar to all of them. I got a web
page that alleges that the nVidia chips are made very poorly. The
picture makes it appear that the chip itself is square with rounded
edges sitting on a small piece of multilevel circuit board much like a
motherboard has.
So I am going to look at mine. It is very possible the nVidia chip
is soldered right to the motherboard. A aluminum heat sink is sitting on
top of the chip. I expect it needs some material between the heat sink
and the chip.
