Solution Change settings in your computer BIOS 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 BIOS setup utility.
For more information on the BIOS setup utility of your computer, see your system manual
or contact your system manufacturer.

Cause Your computer’s other BIOS settings may be incorrect.
1
Solution Reset your computer BIOS settings to the factory defaults using your computer’s built-in
BIOS setup utility. The factory defaults are usually the “safest” settings. Check your system
manual for more information.
Problem Game for Windows 2000/XP doesn’t start or runs slower than normal
(program uses Microsoft DirectX interface)
1
Cause An older version of DirectX may be installed. The Matrox CD-ROM setup program installs
DirectX, but some programs install an older version of DirectX (overwriting your version).
To see what version of DirectX is installed:
1 Access the Matrox PowerDesk Information property sheet (see “Accessing PowerDesk
property sheets”, page 12).
2 Look at the Microsoft DirectX label.
1
Solution If DirectX 8.0 or later isn’t installed, install it. Run the setup program from the DirectX folder
of the Matrox installation CD-ROM.
