That's a known problem with the Nvidia cards used in the XPS (and Sony
Vaio apparently). The problem is that the cards overheat and develop
fractures in the solder 'balls' under the various BGA chips. You can
fix it yourself by removing the heatsink from the card (important*) and
cooking it in the oven for a few minutes to 'reflow' the board. Google
'nvidia reflow' for details.

* if you don't, the force of the heatsink will squeeze the molten solder
from under the chips.
