If you have a nVidia based graphics card, then these are the optimal settings for the BIOS
  1. Make sure the motherboard AGP Bus is set to standard 66MHz,
  2. In motherboard BIOS, enable the following items (if applicable):

    • Assign IRQ for VGA

    • PCI 2.1 compliant

    • PCI or dynamic bursting

    • Bus Mastering for PCI slots

    • Again, in motherboard BIOS, disable the following items (if applicable):

      • Video BIOS shadowing

      • Video BIOS cacheable

      • VGA Pallet Snooping

      • System BIOS cacheable

      • Video RAM BIOS Cacheable

      • Primary/system frame buffer

      • VGA frame buffer

      • Peer concurrency (if your system is full of many peripheral cards, enable it)

      • Power management (if this is an important feature for you, after the problem is fixed, try to enable it back if it does not effect the graphics performance)

      • Write Cache pipelining

      • For "AGP Aperture Size" we recommend setting to the same size as your system memory; but if you see any problems, set it to 1/2 or 1/4 size of your system memory.

      • In Windows, check under device memanger, and make sure there is no device sharing the same IRQ with the GeForce. You may also want to upgrade DirectX to the most current version (available at www.microsoft.com/directx/)
