Troubleshooting and Fixes

Step 1: Verify Game Files

One of the first steps to fix MW3 crashing at the “checking for update” screen is to verify the integrity of your game files. This process will check for any missing or corrupted files and replace them.

Step 2: Check Your Network Connection

A stable internet connection is essential for the update process. Here’s how to ensure your network is not the issue:

• Restart Your Router: Unplug your router, wait for a few minutes, and then plug it back in.
• Use a Wired Connection: If you’re using Wi-Fi, try switching to a wired connection for a more stable and faster internet connection.
• Check for Network Interruptions: Ensure there are no ongoing network issues or interruptions in your area by contacting your internet service provider.

Step 3: Update Your Drivers

Outdated drivers can cause compatibility issues. Ensure your graphics and network drivers are up-to-date:

• Update Graphics Drivers: Visit the website of your graphics card manufacturer (NVIDIA, AMD, or Intel) and download the latest drivers.
• Update Network Drivers: Visit the website of your network adapter manufacturer and download the latest drivers.
• Use Device Manager: Alternatively, you can use Windows Device Manager to update your drivers automatically.

Step 4: Disable Background Applications

Step 5: Adjust In-Game Settings

Sometimes, adjusting the in-game settings can help prevent crashes:

• Disable Overlays: Disable any in-game overlays (such as Steam or Discord overlays) that might be causing conflicts.
• Run in Compatibility Mode: Run MW3 in compatibility mode for an older version of Windows by right-clicking on the game’s executable file, selecting “Properties,” going to the “Compatibility” tab, and selecting an older version of Windows.

Step 6: Reinstall the Game
