Resolved: Garry`s Mod Crashing Problem

Garry`s Mod, abbreviated as GMod, is a popular sandbox game released in 2006. Developed by Facepunch Studios and published by Valve, the game supports both single-player and multiplayer modes and is available for Microsoft Windows, Mac OS X, and Linux.

Several problems have been reported since the game’s release, including Garry`s Mod crashes. Although the game’s developer has released numerous fixes to address these annoying issues, many Windows players still report the crashing problem.

What to do if your GMod keeps crashing? Don’t stress about it! Here are some viable solutions, and you can move on to the next list until the problem is actually fixed.

What causes Garry`s Mod to crash?

Sticky Keys: If you press the Shift key five times in a row, a window prompting you to turn on sticky keys will appear. However, this can also cause Garry`s Mod to crash, so we recommend disabling this key combination.

Incorrect DirectX version: the game may use a version of DirectX that is not compatible with your configuration. Therefore, you should consider changing this setting in the game properties.

Steam Cloud Sync: While this option is very useful for saving important game files online, it causes Garry`s Mod to crash and should be turned off in the game properties.

Sound Settings: The use of surround sound in the game has caused many crashes, according to players. We recommend switching to stereo to see if this solves the problem.

Missing or corrupt game files: In such cases, reinstalling the game or checking the integrity of the game files are two methods that may give you the answer you are looking for.

No administrator privileges: Although games do not require administrator privileges by default, some important game files may be in folders for which the game requires administrator privileges.

How to repair Garry`s Mod crashing issue?

Set your graphics to high settings

If Garry`s Mod does not work on your computer, it may be due to the graphics settings. Some users suggest setting the graphics settings to High, which may solve this problem.

Although changing the graphics settings may result in a lower frame rate, this should solve the problem of crashes.

Check the game cache

  2. Find Garry`s Mod, right-click on it, and select Properties from the menu.

Many games crash when their files are corrupted. So if Garry`s Mod crashes on your computer, you need to check the integrity of the game cache.

Check the cache of other Steam games

Garry`s Mod uses resources from other Source games, and if any of these games have corrupted files, this can cause Garry`s Mod to crash.

After checking Team Fortress 2, move on to checking other Source games.
