Unable to add a video card
On Intel® motherboards, such as the Intel® Desktop Board CA810 and Intel Desktop Board CA810E, the primary video adapter can be changed from the onboard AGP to an add-in PCI adapter through the desktop board BIOS setup utility. The setting is located in the Advanced screen under Video Configuration. The BIOS setup utility can be accessed by pressing the F2 key during system boot. When "Press F2 to enter setup" is displayed on the screen during system boot, press F2 at that time.
For non-Intel motherboards that use the Intel® 810 chipset family, check in the BIOS setup for similar options to those offered on the Intel motherboards. For example: Primary Display Adapter, Video Adapter settings, Primary Video - AGP or PCI, or Onboard video Disable or Enable. Some motherboard manufacturers do not implement this option in their BIOS. Contact the system or motherboard manufacturer for more information regarding BIOS settings.
If there is only a BIOS setting to change the primary graphics adapter, setting this to PCI will not completely disable the integrated graphics adapter, instead, it will set it to work as the secondary adapter for multi-monitor support. If multimonitor support is not desired, the Intel® 810 chipset family graphics driver can be disabled (in software) in Device Manager.
The integrated graphics can be disabled in Device Manager by doing the following:
1) Right-click on the icon for the Intel® graphics controller, then click "Properties".
2) Un-check the item that says "Exists in all hardware profiles"
4) Go back into Device Manager, then back into the properties for the Intel graphics controller.
5) Click the checkbox for the item that says "Disabled in this hardware profile."
If that doesn't work, change the driver for the Intel graphics controller to the Standard VGA driver. If the primary display adapter is set to PCI in the system BIOS, the integrated graphics should automatically show up as disabled in Device Manager after rebooting.
