bought the card new, I had an x1600 pro in it and everything worked fine. Needed a new card for vanguard and 7800gs looked like best bet.
take old card out and put in new card and monitor shows no picture.
ran driver cleaner - didnt help
Tried unplugging everything to see if my psu was problem - no help
got one response on the dell forums from some guy saying that bfg cards have problems with my machine, but that sounds pretty weird to me.
Anyone have any ideas
