1. Install OS. If it's SP1, don't worry. DO NOT have the sound card in the machine yet!
2. Install motherboard drivers from the disc, so you can connect to the internet. DO NOT INSTALL nvidia IDE, firewall or audio drivers. If it shows you a list, uncheck them. If there's no list, click no when it asks you to install.
3. Update Windows. Get SP2 automatically.
4. Download the latest nvidia chipset drivers for 2K/XP, 6.86. Again, DO NOT INSTALL nvidia IDE, firewall or audio drivers.
5. Download and install latest video driver fron nvidia.
6. Disable on-board audio in Windows. Restart.
7. Disable on-board audio in BIOS.
8. Once everything else is OK, then install the sound card.
