Can't 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 auto-detected and you have an on-board video adapter.
- When plugging in the monitor, make sure the cable goes to the new video card and not the onboard.
- 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.
- 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.
- 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.
- 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.
