You need to identify your vga chipset before you can download the correct driver.... Foxconn offers several different vga drivers for this board: (their website is very vague about what the VGA chipset is)
You also need to provide this info when asking for help or drivers for this mb: Socket AM2+/AM2
If you are unable to find a working driver on the manufacturers website, open Device Manager, double-click the video device, click the Details tab and give me the hardware id string that begins with PCI\VEN (1st. line of text only)
Or..... you can click on the HOME button (upper left of this page), click the link for the new beta Driverscan 2011 software, download, install, and run it. It should provide a download link for this driver.
