Common Problems

  • My Diablo IV client is locking up
  • Diablo IV keeps crashing!
  • I'm getting a Fenris error message.

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. Make sure your computer meets the Diablo IV System Requirements. Please note: The game will try to run even if the system doesn't meet our system requirements. This can cause unknown bugs, crashing, or performance issues that may not have a resolution. 
  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.
  4. Run the repair tool to repair any damaged game files.
  5. Overheating can cause performance issues, game crashes, and full computer lockups. Check for overheating components.
Advanced Troubleshooting
  1. Try creating a new administrator account to resolve permissions issues.
  2. Configure your security software's exception list to allow Blizzard applications to run.
  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.
  4. Run ScanDisk and defragment your hard drive to try to repair any bad sectors.
    Note: Do not defragment a Solid State Drive (SSD).
  5. Run the Memory Diagnostic Tool to fix any errors in your computer's physical memory.
  6. If the problem persists, uninstall and reinstall the game.
