The most common reason for this problem is new Nvidia driver updates that do not work well with the game. Other possible causes include broken or missing game files, or the graphics card being overclocked and not stable. These issues can stop the game from starting properly. Now that you know the causes, let’s go through the different methods you can use to solve the issue.
1. Clear Battle.net Cache
The first thing you should try when encountering this error code is clearing the cache of the Battle.net launcher. Most apps save temporary files to your system to help make things run faster, but sometimes these files can get corrupted and cause issues. Since these cache files are temporary, you can safely delete them. The next time you open Battle.net, new cache files will be created automatically.
2. Update or Rollback Graphics Drivers
As mentioned earlier, the error may be related to your graphics drivers, especially if you own an NVIDIA graphics card. Some players have reported that certain driver versions can cause this problem with the game. To fix this, you should either update your graphics drivers to the latest available version or roll back to an earlier version if you already have the latest installed. To do this, visit your graphics card manufacturer’s website, download the appropriate drivers, and install them.
3. Run Windows Memory Diagnostic Tool
Some users have fixed this error by running the Windows Memory Diagnostic tool. This tool checks your system’s memory (RAM) for problems which can sometimes cause crashes like this.
4. Perform a Clean Boot
As previously discussed, a third-party app running in the background could be causing this error. While you could try closing applications one by one, you might not know which one is to blame. This is where doing a clean boot is useful. A clean boot starts your system using only essential Microsoft services, disabling all others. If the game works after a clean boot, you’ll know that one of your third-party apps is the cause. You can then enable services one by one to find the culprit.
5. Reinstall Call of Duty Black Ops Cold War
If none of the above methods have fixed the issue, it’s possible that your game installation has become corrupted. In this case, you’ll need to reinstall Call of Duty Black Ops Cold War. According to reports from other users, reinstalling the game has resolved this problem when nothing else worked, so this might be your solution as well. We hope this guide has helped you fix the 0xC0000005 error code in Call of Duty Black Ops Cold War. If you have any questions or need further assistance, feel free to leave a comment below!
