How to Fix NVIDIA Graphics Card Not Detected in Windows 11

Method 4: Fix Hardware or Software Conflicts

If the previous method didn’t work, then you may need to fix any hardware or software conflicts that may occur between your NVIDIA graphics card and other components in your PC. Hardware or software conflicts can cause performance, stability, or compatibility issues, and prevent Windows 11 from detecting your graphics card.

There are several ways to fix hardware or software conflicts, such as:

• Disable unnecessary devices in Device Manager. Device Manager is a tool that lets you view and manage the devices connected to your PC. You can disable unnecessary devices, such as sound cards, network cards, or USB devices, to reduce the possibility of conflicts with your NVIDIA graphics card. To do this, follow these steps:
  1. Press the Windows key  + X on your keyboard and select Device Manager from the menu that appears.
  2. In the Device Manager window, locate the unnecessary device that you want to disable, such as under the Sound, Video, and Game Cards, Network Cards, or Universal Serial Bus Devices categories.
  3. Right-click on the device you want to disable and select Deactivate Device from the menu that appears. You may be asked to confirm your selection. Click Yes to continue.
  4. Repeat steps 2 and 3 for any other devices that you want to turn off.
  5. Once you disable unnecessary devices, restart your PC and check if your NVIDIA graphics card is already detected by Windows 11.
• Remove unnecessary software in Programs and Features. Programs and Features is a tool that lets you view and remove programs installed on your PC. You can remove unnecessary software, such as programs you rarely use, potentially unwanted programs, or programs that might interfere with your NVIDIA graphics card. To do this, follow these steps:
  1. Press the Windows key  + R on your keyboard to open the Run dialog box.
  2. Type appwiz.cpl in the Run dialog box and press Enter. This will open the Programs and Features window.
  3. In the Programs and Features window, find the unnecessary software that you want to remove, such as under the Name or Publisher column.
  4. Right-click on the software you want to remove and select Uninstall from the menu that appears. You may be asked to confirm your selection. Click Yes or Uninstall to continue.
  5. Follow the on-screen instructions to complete the software removal process.
  6. Repeat steps 3 through 5 for any other software that you want to remove.
  7. Once you have removed the unnecessary software, restart your PC and check if your NVIDIA graphics card is already detected by Windows 11.

Those are some methods you can try to fix the NVIDIA graphics card not detected in Windows 11. We hope one of these methods works for you and you can enjoy a smooth and smooth graphics experience on Windows 11.
