Troubleshooting
Graphics
The following troubleshooting items address problems related to graphics cards.
Problem Computer doesn’t display information or boot after Matrox card
is installed
Cause
Your Matrox card may not be properly installed.
Solution Make sure your Matrox card is properly installed. Specifically, make sure the card
is firmly inserted in its expansion slot and that all connections to it are firmly in
place. For more information, see “Hardware installation”, page 5.
Cause There may be another graphics adapter in your computer. (For Matrox multi-
display mode in Windows NT, all other graphics cards in your computer must also
be Matrox cards.)
Solution If another graphics card is plugged into an expansion slot, remove it.
Solution If a graphics adapter is built-in to your computer’s motherboard, your system may
not have automatically disabled it when you inserted your Matrox card. Check your
system manual for instructions on how to disable your computer’s built-in graphics
adapter.
Cause Your computer BIOS (Basic Input/Output System) may not be up to date. For more
information on your computer BIOS, see your system manual.
Solution Reinstall your previous graphics card and, if possible, update your computer BIOS.
This can usually be done with software from the manufacturer of your computer.
Contact your system vendor or manufacturer to get a BIOS update for your
computer.
To get the correct BIOS update, you may need to know the serial number your
computer displays when it restarts. (This number is usually in the lower-left corner
of the display.)
