How to fix error dxgi-error-not-found in Windows 11

Solution Steps

1. 1 Press Windows key + R to open the Run dialog. Type 'dxdiag' (without quotes) and press Enter. This opens the DirectX Diagnostic Tool, which shows detailed information about your graphics hardware and drivers. Note the 'Driver Version' and 'Date' for your graphics card — you'll compare this to the latest version from the manufacturer's website.
2. 2 Open your web browser and go to the official website of your GPU manufacturer: NVIDIA (nvidia.com/drivers), AMD (amd.com/en/support), or Intel (intel.com/content/www/us/en/download-center/home.html). Download the latest driver for your specific graphics card model and Windows 11 version. Installing the latest driver ensures that any bugs causing the error are fixed.
3. 3 Before installing the new driver, it's best to remove the old one completely. Press Windows key + X and select 'Device Manager'. Expand 'Display adapters', right-click your graphics card, and select 'Uninstall device'. Check the box that says 'Delete the driver software for this device' and click Uninstall. This prevents conflicts between old and new driver files.
4. 4 Run the downloaded driver installer as administrator (right-click the file and select 'Run as administrator'). Follow the on-screen instructions. Choose 'Clean installation' if prompted — this ensures all previous driver settings are wiped, giving you a fresh start. After installation, restart your computer to apply the changes.
5. 5 After rebooting, test the application that was crashing. If the error persists, you can try repairing the game or application. For games on Steam, right-click the game in your library, select 'Properties', go to 'Local Files', and click 'Verify integrity of game files'. This checks for missing or corrupted files and replaces them, which can resolve the error if it was caused by a broken game file.
