[Tfug] anybody have a laptop video card?

[t takahashi]

my dell inspiron 8100's video seems to last only a few minutes from
boot time until it goes black.

in case this is a video card problem, does anybody have a used one
that i can put in there?  i think it is a 32mb agp4x nvidia geforce 2
go. i know little about this stuff.

i figure somebody might have a dead laptop that can be cannibalized. 
i will pay market price.

(of course, it might be random driver corruption and not hardware for
all i know.)
