You may not have to try them all. Just work your way down the list until you find the one that works.

Fix 1: Check your PC specs

If your game crashes or freezes frequently, the first step is to verify your PC is above the minimum system requirements to run Garry’s Mod. If you’re below the recommended spec, try lowering your resolution and graphics and in-game video settings.

Here are the minimum requirements to play GMod:

OS: Windows XP/Vista
Processor:  2 GHz Processor or better
Memory:  4 GB RAM
Graphics:  512MB dedicated VRAM or better
DirectX:  Version 9.0c
Storage:  5 GB available space

Here are the recommended specs to play GMod:

OS: Windows® 7/8/8.1/10
Processor:  2.5 GHz Processor or better
Memory:  8 GB RAM
Graphics:  1GB dedicated VRAM or better
DirectX:  Version 9.0c
Storage:  20 GB available space

Follow the instructions below to view your computer hardware information:

1) On your keyboard, press the Windows logo key and type dxdiag. Then, press the Enter key.

2) Check your operating system, processor, memory and DirectX Version.

3) Check your Display Memory here.

Make sure your computer meets the requirements, then read on and try the fix, below.

Fix 2: Restart your computer

If you’re running multiple programs at the same time, hogging your system’s resources, that could cause your game to crash. In this case, try restarting your computer to end unwanted programs completely, then relaunch your game.

If your problem still exists after the reboot, check Fix 3, below.

Fix 3: Update your graphics driver

Game issues commonly occur when your graphics driver is corrupted or outdated. To see if that’s the problem for you, try updating your graphics driver. There are 2 ways you can do this:

Option 1 – Manually– You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step.


Option 2 – Automatically (Recommended)– This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Option 1 – Download and install the driver manually

The manufacturer of your graphics card keeps updating drivers. To get them, you need to go to the manufacturer support website, find the driver corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update your graphics driver

If you don’t have the time, patience or computer skills to update your graphics driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version– you’ll be prompted to upgrade when you click Update All).

You can do it for free if you like, but it’s partly manual.
If you need assistance, please contact Driver Easy’s support team at

Fix 4: Verify the integrity of your game files

Damaged or missing game files might also cause your game to fail. If you’re running the game on Steam, try verifying the integrity of your game files. Here is how to do it:

1) Run Steam.

2) Click LIBRARY.

3) Right-click Garry’s Mod and select Properties.


5) Relaunch GMod.

If the crashing issue continues to occur, then go ahead with the fix below.

Fix 5: Change the launch option

Many players report that running the game with -dxlevel 85 -console -windowed -noborder launch option fixed the crashing issue. Follow the instructions below to see how to do it:

1) Run Steam.

2) Click LIBRARY.

3) Right-click Garry’s Mod and select Properties.


5) Remove any launch options currently shown. 

6) Type -dxlevel 85 -console -windowed -noborder, then click OK.

Relaunch your game to see if this worked for you. If it didn’t fix your issue, move on to the fix below.

Fix 6: Disable automatic downloads from the server

If you enable the automatic downloads of custom content from game servers, you’re likely to experience this issue when your Internet connection is bad. (This is because the downloading process can hog your Internet speed, thus crashing your game. )

Follow the instructions below to stop the automatic downloads:

1) Run GMod.

2) Navigate to Option, click the Multiplayer tab.

3) Click the list box under When a game server tries to download custom content to your computer, and select Do not download any custom files. Then click OK.

Relaunch your game to check if this has resolved your issue. If not, try the fix, below.

Fix 7: Reinstall Steam

If none of the fixes above worked for you, reinstalling Steam is very likely the solution to your issue. Follow the instructions below:

1) Right-click the Steam icon on your desktop and select Open file location.

2) Right-click the steamapps folder and select Copy. Then, place the copy in another location to back it up.

3) On your keyboard, press the Windows logo key and type control. Then, click Control Panel.

4) Under View by, select Category, then select Uninstall a program.

5) Right-click Steam, and then click Uninstall.

6) Follow the on-screen instructions to uninstall Steam.

7) Download and install Steam.

8) Right-click the Steam icon and select Open file location.

9) Move the backup steamapps folder you create before to your current directory location.

10) Relaunch Steam and your game.
