1. Check Device Driver Updates
Outdated or corrupted drivers are one of the common causes of the Diver error. If your graphics driver is not updated in time, it may become incompatible with the game, leading to crashes or error messages. Therefore, it's recommended to regularly check and update your device drivers. It's recommend to use Driver Sentry to automatically detect and update drivers, saving time and avoiding the risks of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
After the scan is complete, it will show which drivers are missing or need updating. Find the graphics driver in the list and click the "Upgrade" button.
Once the update is complete, restart your computer to ensure the updated drivers take effect.
2. Verify Game File Integrity
For Steam Users:
Open the Steam client and go to your "Library".
Right-click on MW3 or Warzone and select "Properties".
Under the "Local Files" tab, click "Verify Integrity of Game Files".
Wait for Steam to check and fix any corrupted files.

3. Repair System Files
In the search box, type "Command Prompt" and select "Run as Administrator".
In the Command Prompt window, type the following command: sfc /scannow
Press Enter, and Windows will automatically scan and repair any corrupted system files. This process may take a few minutes, so please be patient.
Once the scan is complete, restart your computer and relaunch MW3 or Warzone to check if the issue has been resolved.
4. Check Windows Firewall Settings
Open the Control Panel, click "System and Security", then select "Windows Defender Firewall".

Check if other devices are consuming bandwidth, especially those performing high-traffic tasks (such as streaming video or large file downloads).
Use the ping command to check for network latency:

Check if there are any high latency times or packet loss in the results.
If the network connection is unstable, try restarting the router or use a wired connection to ensure a more stable network environment.
Additionally, make sure there are no active VPNs or proxies, as they can interfere with the game's connection.
