Matrox Graphics Card – User Guide 29
1 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.
3 Cause Windows 98/Me – Other devices in your computer may have IRQs unnecessarily allocated to
them. Each time cards are moved to different expansion slots in your computer, new IRQs
may be allocated without old ones being deallocated.
1 Solution For advanced users – Remove and restore device drivers.
1 Restart your computer in safe mode ( see “Restarting in safe mode”, page 13 ).
2 Click Start # Control Panel # System (double-click) # Device Manager .
3 Under Display adapters , Network adapters , or SCSI controllers , remove any redundant
or unused device drivers. To remove a driver, select its name, then click Remove . (If
you’re not sure whether a driver is redundant or unused, you can remove it. When
Windows restarts, Windows automatically restores needed drivers or prompts you to
reinstall them.)
4 Restart your computer normally.
4 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 98/Me/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 9 ).
Note: Before removing software, make sure you have all the necessary files to reinstall
software that may still be needed.
