Matrox Electronic Systems PCI G450 Solution Change settings in your computer Bios setup utility

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 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.

Solution For advanced users – Remove and restore device drivers.

Note: Before removing software, make sure you have all the necessary files to reinstall software that may still be needed.

1Restart your computer in safe mode (see “Restarting in safe mode”, page 13).

2Click Start # Control Panel # System (double-click)# Device Manager.

(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.)

4Restart your computer normally.

Cause Your computer’s other BIOS settings may be incorrect.

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.
