I start up Garry’s Mod through Steam, and when the background image shows up, with the little “Loading…” box in the bottom left the game crashes and I get a “hl2.exe has stopped responding and needs to close” error. I have already tried verifying game integrity and restarted Steam.

Sucks for you.

Are you on a laptop?
If you are right click gmod in the steam games list and click properties the click launch options the copy and paste this into the textbox:- dxlevel 8.0

Nice to know you guys are helpful.


No. A regular desktop.

Now i feel bad, sorry for not being helpful. 3;

Well its fine, but you really haven’t given any helpful advice yet. D:

I think its the RAM that I have, since I use Vista, but I can’t find why it won’t start.

Restart Steam and PC since this has nothing todo with hardware or garrysmod.

Well I’ve restarted Steam but I’ll try restarting my PC.

Nope. Its still happening.

Have you tried re-downloading Garry’s Mod?

No. I will try that.

Nope. Still get the “hl2.exe has stopped working” error.

You should ask on the Steam forums this is kinda exceeding out knowledge.

Okay. Thanks though.
