Okay, so before installing the new card, you went through: Device Manager and removed your old card, right?
If you didn't. Windoze can be trying to boot with your old card still(yes, even XP has brainfarts), and it just isn't there. Try booting up in safe mode, removing the old drivers, then rebboting again, with the new card.
If you have to, reboot in safe mode, and install the drivers for the new card that way.
I guarantee you have a driver issue.
BTW, welcome to the forums.
