Troubleshooting
This section contains solutions to problems you may encounter with your Matrox Millennium.
Problem: Computer doesn’t boot after Millennium card is installed

Cause – Some computers may not properly detect the addition or change of an internal PCI card.
On start-up, a computer may beep differently from normal to indicate this error.
;
Solution – Reset your computer’s CMOS. This is usually done through a switch or jumper
on the motherboard of your computer. Check your system manual or contact your computer
vendor for instructions on how to do this.

Cause – There may be another graphics adapter in your computer.
;
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 have not automatically disabled it when you inserted your Millennium card. Check
your system manual for instructions on how to manually disable your computer’s built-in
graphics adapter.
