never realised this thread happen..i was one of the victim
my gc died around 7 months ago, 1 year after the date of purchase (few weeks before the 1 year warranty over)

they changed the motherboard and the graphic card (because they are attached together) for free, but with the same chipset..so yeah basically what they have done to me is replacing a defected items with potentially defective items

i lose my hope and respect to dell since then
i understand it is nvidia fault but what annoys me is how Dell handle the problems..much discussion has been made and im not gonna have a war about it once again..whats done is done..and i lose

specs:
Dell Vostro 1400
C2D T5470
GF 8400M GS
Windows Vista Home Basic
1 year limited warranty
