Below are the solutions that you can try if error code 3107840166 has become persistent when playing COD Black Ops Cold War.

Update the game.

Before doing any troubleshooting steps on your PC, be sure to update the COD Black Ops Cold War game. This is especially important if you are getting the error code 3107840166 when playing the offline Campaign mode only. 

For those playing the Black Ops Cold War in online modes most of the time, the game client must already be updated at this time. However, we still highly recommend that you manually check for updates to ensure that you don’t miss anything.

While you’re at it, it’s also important that you update the other applications to lessen the chances of bugs that might cause a problem with your Operating System.

And speaking of your OS, you also want to ensure that it runs the latest Windows update at this time. Although Microsoft regularly release updates, you can also try to manually check for updates anytime to see if there’s new ones that you haven’t installed yet.

Check for the latest graphics drivers.

Once you’ve made sure that the software environment is fully updated, it’s time that you also make sure that the installed graphics card is running the latest driver version. In simple terms, drivers are like mini-OS for a hardware component such as your graphics card that allows smoother communication between the component and Windows OS.

Like your regular Windows Operating System, drivers, especially for the graphics card, have to be regularly updated in order to fix known bugs for certain games. If you only update the game and Windows but leave the graphics card with its older version, your PC may encounter problems when playing new games.
