Do the following:

  1. Delete C:\Program Files\Steam\Steamapps\username\garrysmod*garrysmod* to eliminate the possibility of addons. If it still does it, you can restore it from recycling bin and get your addons back.

  2. Delete clientregistry.blob. The file isn’t really associated with this kind of problem but its worth a shot. Its located in C:\Program files*steam*.

If these two dont work, consider the following:

1)Do you have another game w/ the source engine? Is it fully working or do you get the same problem? If you have no other source games, Garry’s Mod will not start.

2)Do you meet the system requirements? If not there is a possibility your computer will fail.

3)Try reinstalling the game and verifying the game cache (right click the game choose properties goto local files and choose verify integrity of game cache.

4)Try uninstalling every game associated with HL2 (the episodes and hl2), reinstalling them and then garrysmod AFTER installing those.
