I would try going into the System applet and deleting the reference to the card and then shutting down the PC,,
then I would reboot the machine and go throught the ADD HARDWARE WIZARD in XP and manually identify the card for what it is,,
use the have disk, and run the driver,, (look for the updated version on the web)
see what happens,,,
some times plug and play is still plug and pray,,
