Can't add video card to computer that has on-board video

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

  1. When plugging in the monitor, make sure the cable goes to the new video card and not the onboard.
  2. Verify with the computer's documentation or the manufacturer that there are no jumpers to disable the on-board video adapter or required settings changes in CMOS setup. Nearly all modern computers automatically disable the on-board video when a card is installed.
  3. Check to see 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.
  4. If you have Windows 95, Windows 98, Windows ME, Windows 2000 or Windows XP, before adding the card within Windows, disable the on-board video. To disable on-board video, open Windows Device Manager and click the plus by Display Adapter. Within the Display Adapter menu, double-click on your on-board video and place a check in the box to disable in hardware profile (located near the bottom). Shut Down the computer and physically install the new video card.
  5. If none of the above recommendations resolve your issue, it is recommended that you contact the manufacturer of your computer or video card.

Tip: When purchasing a video card for a computer that has on-board video, it is highly recommended that you purchase a brand of video card that different than that which came pre-installed. Having two video adapters from the same manufacturer is a common reason why the on-board video card may not be disabled automatically.
