First, make sure that your graphics card is properly installed in the system. If it was recently installed, make sure all the connectors are firmly in place and that the card is properly seated in the slot. Also check to ensure that the power cable is connected to the correct power source.
If your graphics card still isn’t being recognized, try running the hardware troubleshooter. To do this, open the control panel and click on “Troubleshooting” under the “System and Security” section. In the troubleshooting window, select “Hardware and Sound” and then select “Check for hardware changes”.
If that doesn’t work, you may need to update your drivers. To do this, go to the website of your hardware manufacturer and download any updated drivers for the cards. You can do this manually or run a driver updater software, such as Driver Booster or Driver Easy, to scan for any available updates.
If the update does not work or your graphics card is not listed, you may need to consider replacing it. Make sure to check compatibility with your motherboard before buying a new one.
If you’ve done all of the above and your graphics card still isn’t working, there may be a hardware issue. Check whether the card is properly connected to the motherboard and try reseating it if necessary. If that doesn’t work, you should try a different PCI slot or even a different PC altogether.
If the above steps don’t help, the graphics card could be faulty and require repair or replacement. If you’re unable to diagnose and fix the problem yourself, contact the manufacturer of your graphics card and ask for help.
