Not Enough Memory

You will see this error when your computer runs out of space for new information in its memory. To troubleshoot this error, follow the steps below.

Note: A computer's storage is different from the computer's memory. If you don't have enough space on your hard drive, see the Insufficient Space on Your Hard Drive article.

1. Close all other applications to resolve software conflicts and free up resources.
2. Reset your user interface to make sure your files and addons are not corrupted.
3. Try reducing graphics settings within the in-game System menu. This will lower the game’s demand on your computer and save memory. High Definition Textures, Texture Quality or View Distance settings can be particularly memory intensive.
4. If you are using a 32-bit version of Windows, we recommend upgrading to a 64-bit operating system as 32 bit is unsupported. This will allow your computer to use much more memory and should permanently resolve this error.

If you get this error and cannot run a game, please ensure your computer meets all of the listed system requirements (World of Warcraft, StarCraft II, Diablo III, Hearthstone, Heroes of the Storm, Overwatch).
