If you experience a crash with a blue or black screen error message, a crash to your desktop, or if your computer locks up while playing World of Warcraft®, make sure your computer meets the World of Warcraft System Requirements.

If your system meets these requirements, follow the steps below to resolve the issue.

Windows

  1. Issues with temporary game files may cause crashes and lockups. Try resetting your user interface to clear out these files.
  2. The game requires an up-to-date operating system and up-to-date drivers to run smoothly. Check for updates before continuing.
  3. Programs running in the background can interfere with the game. Close any running background applications.
