I presume that you are switching betwwen cards after post. Been there and done that. The Dell card is, as the quote above suggests, Doggie Doodoo! The fact that it crashes when the generic drivers at post are replaced by manufacturers drivers indicates that that card probably has bad GDR memory. Buy a new card. If you have the money, buy a 7900GT.
