So at the office i work at we are trying to install new graphics cards into the computers that we use for CAD(drafting). the old cards were nvidia quadro fx 3450. Here is step by step what happened. First we took out the old nvidia card, installed our new Sapphire hd 6870 card and booted up. we were about to install the new drivers when we realized we needed to uninstall the nvidia drivers. so we shut the computer down, put the nvidia card back in, booted up, and uninstalled everything nvidia from add/remove programs. shut the computer down, installed the 6870 and booted. we then tried to install the drivers from the disk. the driver installation gets about halfway down and then crashes and the BSOD shows up saying there is some faulty driver issue. we restarted and tried getting the drivers from the amd site directly and the same thing happened. we are running out of ideas on how to fix this. it is very time sensitive since if we can not get thtese cards to work we need to return them to newegg before the return policy runs out. the computers were custom builds FROM DELL. these were not built part by part like a gaming pc may be built. its dell parts, dell case, etc. the ram has been upgraded to 8 gigs and the power supply has been upgraded to a 500W. any help would be veryyy greatly appreciated.

have you tried to put the old card back in and trying to install nvidia drivers again?

is there any onboard graphics on the mobo?

try driver sweeper and uninstall everything graphics related and try installing drivers again.

I have had experience with Dell and thier computers and is the reason I started to build my own. They are hard to work on because they build them a certian way. I would recomend you call Dell tech support and see if they can help.

to see if something got damaged because you switched I guess but you should try driver sweeper first.
