Could you please first of all tell us which Operating System you are using? If you are on vista then you can try installing the driver for your display card and motherboard in Compatibility mode. Remove that hardware device in Device Manager, right-click on the driver executable/installer file and select the Compatibility tab; click the checkbox before Run this program in Compatibility mode for option and select Windows Vista in the list-down box; then try installing the device driver. In addition, you can use the Windows XP driver for testing.
