What You’ll Need

• Administrator access to your Windows PC
• Internet connection for updating drivers and Windows
• Game files or Steam/Battle.net launcher (if applicable)
• Optional: Backup of important system files or create a system restore point

Step-by-Step

1. Close all background applications and restart your PC. Before troubleshooting, ensure no unnecessary programs are running to prevent conflicts. Restart your PC to clear temporary files and refresh your system state.
2. Update your graphics drivers. Outdated or corrupted graphics drivers are a common cause of this error. Visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) and download the latest drivers. Alternatively, use Device Manager:
   • Press Windows key + X and select ‘Device Manager’.
   • Expand ‘Display adapters’.
   • Right-click your graphics card and choose ‘Update driver’.
   • Select ‘Search automatically for updated driver software’ and follow prompts.
3. Run Windows Update. Ensure your Windows system is fully updated, as updates often include important fixes for compatibility and security:
   • Open Settings (Windows key + I).
   • Navigate to ‘Update & Security’ > ‘Windows Update’.
   • Click ‘Check for updates’ and install any available updates.
4. Verify game files integrity. Corrupted game files can cause errors. If you’re using Steam:
   • Open Steam and go to your Library.
   • Right-click on Call of Duty: Vanguard and select ‘Properties’.
   • Navigate to the ‘Local Files’ tab and click ‘Verify integrity of game files’.

   If using Battle.net, click on the game, then select ‘Options’ > ‘Scan and Repair’.

5. Disable overlay programs and third-party apps. Overlays from Discord, NVIDIA GeForce Experience, or other software can interfere. Disable them temporarily:
   • For Discord: go to User Settings > Overlay > Turn off ‘Enable in-game overlay’.
   • For NVIDIA GeForce Experience: open GeForce Experience > Settings > General > Disable in-game overlay.
6. Adjust Windows graphics settings. Set the game to run with preferred graphics processor:
   • Right-click on the game executable or shortcut.
   • Select ‘Run with graphics processor’ > ‘High-performance NVIDIA processor’ or equivalent.
7. Reinstall the game if the error persists. As a last resort, uninstall and reinstall the game to ensure all files are correctly installed and no corruption remains.

Common Mistakes

• Ignoring driver updates—using outdated drivers can cause compatibility issues.
• Disabling Windows updates—missing critical patches can lead to errors.
• Overlooking overlay conflicts—third-party overlays often interfere with game launch.
• Skipping game file verification—corrupted files can cause persistent errors.
• Running the game without administrative rights—this can prevent proper file access and updates.

Tips

• Always run your game as an administrator to prevent permission issues.
• Create a system restore point before making major changes, so you can revert if needed.
• Keep your graphics drivers and Windows system updated regularly for optimal compatibility.
• Disable unnecessary background applications to improve performance and reduce conflicts.
• Check official forums or support channels for any ongoing server or software issues affecting the game.

Troubleshooting

If the error persists after following the above steps, consider the following troubleshooting options:

• Perform a clean boot: This helps identify if third-party services or startup programs are causing conflicts. To do this:
  • Press Windows key + R, type ‘msconfig’, and press Enter.
  • Go to the ‘Services’ tab, check ‘Hide all Microsoft services’, then click ‘Disable all’.
  • Go to the ‘Startup’ tab and click ‘Open Task Manager’.
  • Disable all startup items.
  • Restart your PC and try launching the game again.
• Check for Windows system file corruption: Open Command Prompt as administrator and run ‘sfc /scannow’. This scans and repairs corrupted system files.
• Reset display settings: Sometimes, resetting your display configuration can resolve graphics-related errors.
  • Right-click on the desktop and select ‘Display settings’.
  • Adjust resolution and scaling to recommended settings.
• Contact support: If none of the solutions work, contact Activision support or visit official forums for tailored assistance.
