I had a similar problem installing an older card to run a 2nd monitor.
I had to turn off the computer, take the card out again, then reboot and install the drivers. Turn computer off again, replace the card and reboot then it found the drivers.
This might be worth trying, it worked for me. I don't know why!
Observe all the usual precautions when playing in the inside of computer. Good luck!
