Solution Steps
- 1 Run the System File Checker: Press Windows key + X and select 'Terminal (Admin)'. Type 'sfc /scannow' and press Enter. This scans and repairs corrupted system files that might cause the error. Wait for it to complete (may take 15-20 minutes).
- 2 Run DISM: In the same terminal, type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This repairs the Windows system image. It's a deeper repair that ensures system files are healthy.
- 3 Check your RAM: Press Windows key + R, type 'mdsched.exe' and press Enter. Choose 'Restart now and check for problems'. Windows will test your RAM for errors. If errors are found, you may need to replace the faulty RAM stick.
- 4 Verify game files: If the error occurs in a specific game, open the game launcher (Steam, Epic, etc.) and use the 'Verify integrity of game files' option. This checks for corrupted game files and re-downloads them.
- 5 If you use mods, disable them temporarily. Mods can cause access violations if they're incompatible with the game version. Remove mods and test the game.
- 6 Update your graphics driver and DirectX: Go to your GPU manufacturer's website and download the latest driver. Also, download the latest DirectX runtime from Microsoft's website.
