Therefore, we've provided a detailed breakdown of all the effective ways to prevent Modern Warfare 3 beta from crashing on PC.

How to stop Modern Warfare 3 Beta crashing on PC (MW3)

Here are a few ways through which you can fix crashing issues in Modern Warfare 3 beta:

• Check your system requirements
• Update graphics driver
• Update Windows
• Verify the game files
• Contact Activision support

Check your system requirements

To run Modern Warfare 3 beta without any crashing issues, you should first make sure your PC meets the following minimum system requirements:

• Operating system: Windows 10, 11 (64 bit)
• Processor: Intel Core i5-6600 or AMD Ryzen 5 1600
• Graphics card: NVIDIA GeForce GTX 1060 or AMD Radeon RX 580
• Video memory: 6GB
• RAM: 16GB
• DirectX: 12
• Hard Drive Space: 65GB on SSD (25GB with Call of Duty HQ installed)

If your system does not meet these requirements, you might need to upgrade your hardware in order to play the game.

Update graphics driver

If you continue to experience crashing issues while playing MW3 beta, one possible reason could be incompatible drivers. To avoid this, ensure you have the latest drivers by visiting the websites of your GPU manufacturer (e.g. AMD, NVIDIA, or Intel) or using third-party software like Driver Booster to check for updates.

Update Windows

An outdated operating system could cause random in-game crashes. Therefore, keeping your Windows up-to-date can improve your computer's performance by fixing bugs and resolving compatibility issues. To check for Windows updates, head to the Start menu >> settings icon >> Update & Security >> Check for updates.

Alternatively, you can also access the Windows Update settings by searching for "Windows Update" in the Start menu search bar or by going to Control Panel > System and Security > Windows Update.

Verify the game files

Video Games usually crash when one of the game files is missing or corrupted, and the MW3 beta is no different. Instead of reinstalling the game, verifying the game files is the best way to rule out this case. 

Follow these steps to verify game files in Battle.net:

1. Open the Battle.net desktop app on your PC.
2. Click on Call of Duty under the library section.
3. Click on the Options button (represented by a gear icon) located next to the Play button.
4. Select Scan and Repair from the drop-down menu.
5. Click on Begin Scan and wait for the process to finish.

Follow these steps to verify game files in Steam:

1. From the Library section, right-click on the game and select Properties from the menu.
2. Select the Local files tab and click the Verify integrity of game files... button.
3. Steam will verify the game's files. This process may take several minutes.
