Solution
Change settings in your computer’s CMOS setup utility.
If your computer has the options of enabling Plug-and-Play detection, or assigning an IRQ
to a VGA adapter, make sure they’re enabled. If your computer doesn’t have these options,
you may be able to manually assign an IRQ to your graphics card using the CMOS setup
utility.
For more information on your computer’s CMOS setup utility, see your system manual or
contact your system manufacturer.
