How do I fix a graphics card that is not recognized by Windows?

1. Check Device Manager

The first step in troubleshooting a graphics card that is not being recognized by Windows is to check the Device Manager for any errors. If the Device Manager does not show any information about the graphics card, or shows an error message, then it is likely that the device is not being recognized by Windows.

2. Check the Graphics Card Connections
If the Device Manager does not show any information about the graphics card, it may be due to a loose connection. To check this, open up the computer and make sure that all of the connections for the graphics card are firmly connected.

3. Check the Power Supply
If the graphics card is still not being recognized by Windows after checking the connections, it is likely due to a power supply issue. Make sure that the power supply is compatible with the graphics card, and that the power supply is providing enough power to the graphics card.

4. Update the Graphics Card Drivers
If the graphics card is still not being recognized after ensuring that all connections and the power supply are working properly, it may be due to outdated drivers. Try updating the drivers for the graphics card by going to the manufacturer’s website and downloading the latest drivers.

5. Reinstall the Graphics Card
If the drivers have been updated and the graphics card is still not being recognized, try uninstalling the graphics card from the Device Manager and then reinstalling it. This will allow Windows to detect the graphics card and install the correct drivers.

6. Disable Onboard Graphics
If the graphics card is still not being recognized, and the above steps have failed, it may be due to the onboard graphics being enabled. To disable the onboard graphics, go into the BIOS settings, find the section for on-board graphics and disable them. After disabling the onboard graphics, restart the computer and see if the graphics card is now being recognized by Windows.

7. Replace Graphics Card
If all of the above steps have been unsuccessful, it may be necessary to replace the graphics card with a new one. Before replacing the graphics card, double check that all connections and the power supply are working properly. Also, be sure to get a new graphics card that is compatible with the computer, and that has the correct drivers for the operating system.
