Use the 30-82 detonator drivers, not the latest 4 series for your video Ti Card. Works much better. Let the program control anti-aliasing in the vid settings for Nvidia.
Reserve a slot for the nic lan card in bios and get the interupt shifted. If necessary you may have to pull all the cards out except video and remove them from the system listing and let windows re-install video first, then add sound card (if onboard sound it will install anyway), and lastly the NIC in a reserved slot specified in bios. You can determine which slot to reserve once the video and sound is installed. Look under PCI/Legacy configuration info in the advanced chipset options in Bios.
Though my cards share PCI IRQ steering and a host USB controller (10), my NIC, sound and video are on different irqs.
e.g. Netgear card= 9 (irq 9 reserved in bios for the NIC slot), Audio=10 (auto), video Geforce Ti =11 (auto)
Video will usually be 10 or 11 on pnp.
