Cant add video card to computer that has on-board video

Below, is a listing of suggestions to try if your new video card is not being auto-detected and you have an on-board video card.

  1. When plugging in the monitor, make sure the cable is being connected to the new video card and not the onboard video card.
  2. Verify with the computer's documentation or the manufacturer that there are no jumpers to disable the on-board or setting in CMOS setup. Today, with most modern computers the computer should automatically disable the onboard video card when a new video card is installed.
  3. Verify if the video card you are attempting to install has jumpers or dip switches to change its resources that it is set to auto-detect. If there is no auto-detect option and the video card is not being detect you may also want to try other settings (if available).
  4. If you have Windows 95, Windows 98, Windows ME, Windows 2000 or Windows XP, before adding the card within windows, disable the onboard video. To disable onboard video open Windows Device Manager, click the plus by Display Adapter, double-click on the video card under Display Adapter, and place a check in the box to disable in hardware profile (towards the bottom). Shut Down the computer and install the video card into the computer.
  5. If none of the above recommendations resolve your issue, it is recommended that you contact the computer manufacturer for additional help and recommendations.

Tip: When purchasing a video card for a computer that has on-board video, it is highly recommended that you do not purchase the same brand of video card that came pre-installed. This is a common reason why the on-board video card may not be disabled automatically.
