Your motherboard is based on an ATI chipset so you are best to download the drivers for your system from ATI.
Assuming you are using the integrated ATI graphics and are running windows XP (will also work with Windows 2000) here's a link to the latest Windows XP full package:
This package includes: Display Driver, Control Panel, GART Driver, South Bridge driver.
If you have a separate graphics card then you only need the GART Driver and the South Bridge driver. To find the separate files and for future updates go to click here, click "Drivers & Software", click "Windows XP Drivers and Software", click "Motherboards with ATI Graphics", then click the latest CATALYST drivers (currently "CATALYST 5.4 Windows XP - Motherboard/IGP Drivers"). There are links for the full package or split in to the 4 components here.
