Call of Duty Blacks Ops Cold War Error Code 0xC0000005

As it turns out, Call of Duty Blacks Ops Cold War has been out for quite some time now and while it has been running fine for most of the users, there are some who stumble upon an issue every now and then. The reason that you might be stumbling upon the said error code can really differ as there are multiple factors that come into play here. As such, in order for you to understand what exactly is causing the error code, let us first go through the possible list of causes before jumping into the different methods that can help you fix the issue. So, without further ado, let us get started.

  • Third Party Interference — The first reason that the error code in question may occur is when you have third party applications running in the background interfering with the game process. In such a scenario, you will have to close the culprit apps in order to resolve the issue.
  • Graphics Drivers — As it turns out, in some cases, the problem can also originate due to the graphics drivers that are installed on your system. If this happens, you will have to either rollback your drivers or install the latest version available.
  • Battle.net Cache — In addition to that, the temporary files stored by the Battle.net launcher on your PC can also result in the error code mentioned above. In such a scenario, you can clear out the cache files to resolve the issue.

Now that we have gone through the possible list of causes, we are finally ready to go through the different methods that are available to you in order to circumvent the issue. With that said, let us jump right into it.

Clear Battle.net Cache

As it turns out, the first thing that you should do when you encounter the error code in question is to clear out the cache of the Battle.net launcher. Most of the apps that you use on your system store temporary files for different purposes but the general purpose is to make the overall experience smoother for you while you are using the particular app.

Since these files are temporary, you can easily delete them and they will be created again the next time you open up the application. To clear out the Battle.net launcher’s cache, follow the instructions given down below:

  1. First of all, make sure that the Battle.net launcher is not running on your system. In addition to that, ensure that no processes related to Battle.net are running by opening up the Task Manager.
  2. After you have done that, go ahead and open up the Run dialog box by pressing Windows key + R on your keyboard.
  3. In the Run dialog box, type in %ProgramData% and then hit Enter.
    Opening up Program Data Folder
  4. Once you have done that, locate the Battle.net folder and delete it in the File Explorer window.
  5. After that, go ahead and launch the Battle.net Launcher and see if the problem is still there.

Change Graphics Drivers

Another reason, like we have mentioned, that the error code in question may appear is due to the graphics drivers that are installed on your system. This mostly applies to users that own an NVIDIA graphics card and, naturally, have NVIDIA drivers installed. There have been reports of certain driver versions causing the mentioned issue with the game from multiple users.

In such a scenario, to resolve the problem, you will either have to install the latest version of the graphics drivers on your system or rollback to an older version if you are already on the latest version. You can do this by searching for the available drivers on your manufacturer’s website and downloading them from there. To uninstall your graphics drivers, follow the instructions given down below:

  1. First of all, open up the Device Manager by searching for it in the Start Menu.
    Opening up Device Manager
  2. On the Device Manager window, expand the Display adapters list.
    Device Manager
  3. Right click on your graphics drivers and from the drop down menu, choose the Uninstall device option.
    Uninstalling Graphics Drivers
  4. After that, go ahead and download another version of the drivers from your manufacturer’s website and install them.
  5. See if that resolves the problem for you.

Run Windows Memory Diagnostic Test

As it turns out, some users, who were facing the similar issue, have reported that they were able to resolve the problem in question by running the Windows Memory Diagnostic tool on their system. Windows Memory Diagnostic tool essentially checks the memory in your system for any issues. To run the tool, follow the instructions given down below:

  1. To start off, open up the Start Menu and search for Windows Memory Diagnostic and open it up.
    Opening up Windows Memory Diagnostic Tool
  2. On the dialog box that appears, click the Restart now and check for problems (recommended) option provided.
    Windows Memory Diagnostic Tool
  3. Your PC will now restart and the test will begin. Wait for it to complete.
  4. Once the test is complete, your system will boot into Windows and you will be notified of the result in a system notification.
  5. After you have done that, go ahead and try launching the game to see if the problem has been solved.

Perform a Clean Boot

As we have mentioned earlier as well, one of the reasons that the error code mentioned above comes up is due to the interference of a third party app that is running in the background. When this happens, you will have to simply close out the program that is causing the issue.

However, the problem here is that you might not know which app or service is actually causing it. This is where clean boot comes in handy. When you perform a clean boot, your system is essentially started with only the required services running and everything else is blocked. Thus, if the problem does not appear in clean boot, you will know for certain that the issue is indeed being caused by a third party app. If this case is applicable, you can enable the services one by one to figure out the culprit. Follow the instructions down below to perform a clean boot:

  1. First of all, open up the Run dialog box by pressing Windows key + R on your keyboard.
  2. In the Run dialog box, type in msconfig and then hit the Enter key.
    Opening up System Configuration
  3. On the System Configuration window, switch to the Services tab.
  4. There, go ahead and tick the Hide all Microsoft services checkbox.
    Hiding Microsoft Services
  5. After that, click the Disable all button provided and follow it up by clicking Apply.
    Disabling Third Party Services
  6. Once you have done that, switch to the Startup tab and click the Open Task Manager option.
    System Configuration Startup Tab
  7. On the Task Manager window, select all of the apps one by one and click Disable.
    Disabling Third Party Apps
  8. After doing that, go ahead and restart your PC.
  9. Once your PC boots up, try launching the game to see if it encounters the issue.

Reinstall Call of Duty Black Ops Cold War

Finally, if none of the methods have fixed the problem for you, then it is very likely that the problem is being caused by the installation files of the game. In such a scenario, you will have to, unfortunately, reinstall the game on your system. As per other user reports, reinstalling the game has fixed the problem for many when nothing else worked so that might just be your way back in as well.
