Problem
Computer doesn’t display information or boot after Matrox card is
installed
1
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 4
.
2
Cause
If you have more than one PCIe ×16 slot, your graphics card may be using a slot that doesn’t
have 16 lane support.
1
Solution
Try moving your PCIe card to another PCIe slot in your computer. For more information on
the PCIe support of your system, see your system manual.
3
Cause
There may be unsupported graphics hardware in your computer.
1
Solution
If an unsupported graphics card is plugged into an expansion slot, remove it.
2
Solution
If graphics hardware is built into your computer 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 hardware.
4
Cause
Your computer BIOS 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.)
