How to disable on-board VGA card my machine Gateway E-4620d I have installed a External NIVIDIA Graphics Card into my machine Gateway E-4620d how disable on-board VGA

The HD3200 on-board (integrated on the motherboard) graphics on this older machine will not support many games. You need to add a separate graphics card to this unit and disable the on-board graphics. Decide on how much you can afford for a new card and check out tomshardware.com VGA charts to see the best performing video card in your price range. You might also consider a newer machine as this is probably about 5 years old. Whatever machine you get, make sure you do not depend on on-board graphics if you want to do gaming.

1.5.1 Graphics Subsystem
The board contains two separate, mutually exclusive graphics options. Either the integrated
graphics processor (contained within the ATI Radeon Xpress 200 Northbridge) is used, or a PCI
Express x16 add-in card can be used. When a PCI Express x16 add-in card is installed, the ATI
Radeon Xpress 200 Northbridge graphics controller is disabled.

some bios settings disables the add on video cards. to enable them go to bios setting by pressing DEL or F12 while power on your system. (u will see that a message appears "press ----- Key to enter bios settings). after entering bios setting u will see onboard VGA enable/disable. u have to disable onboard VGA in order to get the display thruogh VGA card.

Hello, Your on-board vga is still active and by default your computer will use this for displaying graphics. You will need to disable it to use your new card or change priority so that it searches for an external display first. To do this restart your computer, go into the bios and turn it off or change priority. Refer to your computer manual for the proper location of this setting.
Please bear in mind that some systems do not give you the option of disabling your on-board vga. I believe this is to allow you to still use your computer should the external vga fail.

Hope this helps, thanks for using FixYa

Your board has ATI integerated graphics, no need to remove. You would upgrade by adding a PCIe express card in slot. Do you have such a card? If you need installation instructions, let me know at "add a comment"

Friend,
There are three PCI slots on yoyr motherboard. You can add any PCI VGA card to your board. After adding the VGA goto BIOS setup and make ON BOARD VGA DISABLED.

Thanks & Good Luck

yep. try disable on board card (if there is a setting) and use external video card.

Disable on board VGA card through the bios. Add your pci-e video card to the pci-e slot. Thats it.
