Common Problems

Before trying any of the following steps, check the BlizzardCS Twitter and bug report forums for known issues for your game. Select your game from the dropdown at the bottom for game-specific troubleshooting, which is often helpful when the standard troubleshooting fails.

If you experience a crash with a blue screen error message, follow the steps in our Blue Screen Crashes article. If your computer locks up while running the Battle.net App, follow the steps in our Computer Restarts or Shuts Down article. Otherwise, follow the steps below to resolve the issue.

  1. If the Battle.net App is still downloading game data, allow it to finish the installation and try again.
  2. Update your drivers and operating system to resolve any compatibility issues.
  3. Close all other applications to resolve software conflicts and free up resources.
    Note: This includes any Overlay programs you may be running.
  4. Run the repair tool to repair any damaged game files.
  5. Try creating a new administrator account to resolve permissions issues.
  6. If you're playing on a laptop, optimize your power management settings and graphics options.
Advanced Troubleshooting
  1. Update or temporarily uninstall any security programs, which may mistakenly identify game client as a security threat.
  2. Set your components to factory default speeds to resolve overclocking related stability issues
  3. Changes to the software settings on your video card drivers may cause crashes or performance issues. Reset your video driver settings to correct this problem.
