1. When you removed the old video card, did you go to both device manager, and add/remove programs to uninstall all software related to the old card?
Even if the old card was a different Nvidia based card, this is a good idea.
2. Have you tried updateing the AGP mini-port driver for the motherboard?
Updateing the motherboard drivers may correct the problem.
3. What version of DirectX is installed?
Many new video drivers require version 8.1
4. Have you checked with the motherboard mfg for a BIOS update?
I have seen many a BIOS update that specifically mentions a improving compatability with Nvidia video.
5. Have you downloaded the latest Nvidia driver?
And, Creative drivers?
6. Have you tried the sound card in a different slot?
Even with IRQ steering, and even in XP, it often helps correct a conflict by changing the slot a card is in.
Be sure to remove the card(s) from device manager before changing the slot, as Windows can do some strange things if you just move the card to a different slot.
Also, if an ATX style system, remember to turn off the power supply before unplugging cards.
The next step would be to scan through the registry and delete any keys for the old video card. CAUTION!!! IMPROPER EDITING OF THE REGISTRY CAN CAUSE WINDOWS TO NO LONGER BOOT!!!
Backup the registry before editing.
