Fix 1: Close all background Apps and repair your game

When it comes to video game crashing, the most possible cause is your graphics driver. A Graphics card (GPU) is the most important component to determine your gaming performance. Therefore, if the graphics driver is outdated or corrupted, it’s very likely that you will get enormous Modern Warfare crashing. Modern Warfare crashing can be caused by corrupted graphics card drivers.

To update your graphics driver, you have two options: manually or automatically.

Option 1: Update your graphics driver manually

Download the latest & correct graphics driver from the manufacturer’s website:

• NVIDIA
• AMD

Once downloaded, open the driver file and install the latest driver manually.

The manual updating process is time-consuming. You’ll need to check for updates again and again since the graphics card manufacturers keep releasing new drivers to fix bugs and improve performance for certain games. You may be amazed at how often you miss a driver update for your graphics card.

Option 2: Update your graphics driver automatically

Updating your graphics driver automatically is quite easy. Simply download and run Driver Easy, and it will recognize your system and find the correct & latest driver for it. Also, you can also update other related drivers such as audio driver, keyboard driver, etc.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to your graphics card to download the latest and correct driver for it, then you can manually install it.

OR

Click the Update All button at the bottom right to automatically update all outdated or missing drivers on your computer (this requires the Pro version, which comes with Full Support and a 30-day Money Back Guarantee. You will be prompted to upgrade when you click Update All).

4) Restart your PC for the changes to take full effect.

Fix 3: Set texture quality to high or normal

Many Call of Duty players may set their graphics settings to Low, which can be the culprit of the Modern Warfare crashing issue. Modern Warfare may crash for not having enough texture quality, especially if you get an error code Dev Error 6178. Many gamers find setting Texture Resolution to Normal or High solved their crashing issues, depending on your PC specs.

Here’s how to do it:

1) Open your Call of Duty: Modern Warfare and go to Options > Game Settings > Graphics.

2) Under the Details & Texture tab, set Texture Resolution to High or Normal.

Play Modern Warfare again to see if the crashing issue persists.

This is the method you can always try when you run into game crashing issues. Corrupt game files can cause Call of Duty: Modern Warfare crashing issues.

If you’re using any programs with overlay features such as Discord, disable the In-Game Overlay as it will cause random game crashes on your PC.

1) Open Discord and click the settings icon.

2) Navigate to the Overlay tab on the left pane.

sfc /scannow

• no errors
• it fixed some errors
• could not fix all errors
• could not fix errors at all
• ……

No matter what message you receive, you can try running dism.exe (Deployment Image Servicing and Management) to further scan the health of your PC.

Step 2. Run dism.exe

1) Run Command Prompt as admin and enter the following commands.

• This command line will scan the health of your PC:

dism.exe /online /cleanup-image /scanhealth

• This command line will restore the health of your PC:

dism.exe /online /cleanup-image /restorehealth

2) After the restore health process finishes, you may get some error messages.

• If restore heath gave you errors, you can always try this command line. This will take up to 2 hours.

dism /online /cleanup-image /startcomponentcleanup

• If you get Error: 0x800F081F with the restore health scan, reboot your PC and run this command line.

Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore
