FATAL ERROR on Warcraft III
Here are ways to solve Fatal Errors when you meet them:
(RAM) OR SYSTEM MEMORY
This solution is recommended for advanced users only. We have gotten reports of crashing, freezing, and memory read error messages being solved by removing bad or mismatched RAM from machines. You may want to remove one stick of RAM at a time and see if this corrects the crash. If you would like to test your RAM to make sure it is performing as it should you may want to run a RAM testing program. If you need a program to do this try doing a search on the web or consult your local computer technician. Unfortunately we cannot provide support for using these programs but they should come with well documented readmes to get you started on how to use them.<

Maphacking
It is known that maphack causes fatal errors to Warcraft 3 randomly. Close your maphack and make a better gaming world for all.
Custom Map Memory Leaks
Due to the flexibility of the triggers in the Warcraft III Map Editor, it is possible to make triggers that can cause the game to crash. If you are experiencing crashing while playing a custom made map please try playing a Blizzard designed map - this will help to determine if the issue is related to the custom map or a possible conflict.
Outdated Game
Please install the latest game patch. It includes several fixes that may correct this type of error. You can patch the game by connecting to Battle.net for the auto-patch or you can download and run the stand-alone patch from the Warcraft III Patch Page.
Background Applications
Usually Background applications take up a lot of memory space and causes these problems.Use Ctrl + Alt + Del and close certain programs that are not important to the Computers security and stability.
Registry File
This solution is only for players whose Warcraft III crashes at startup.
