[SIZE="5"]Possible Reason Number 1.[/SIZE]
If you have too much addons that can be a problem if you didn't update your addons with svn recently. If the addons you added were from garrysmod.org. You have to delete it. Reinstall it using SVN.The Latest Version & it should be fine.

[SIZE="5"]Possible Reason Number 2. In Most Case For Most Source Games.[/SIZE]
If you have added any Counter-Strike:Source, Team Fortress 2, Day Of Defeat:Source as your Addons Extension for Gmod. Then you should really Disk Defrag.To do this on steam go to your games by right clicking your games. Properties, Defrag Caches.Because recently Team Fortress has been getting alot of updates, same as Counter-Strike:Source.For weekly disk defrag to keep your computer running smooth like me. I recommend Auslogics Disk Defrag fast and easy. Disk Defrag & Optimize http://download.cnet.com/Auslogics-Disk-...?tag=mncol.Oh yeah don't forget to disk defrag your PHX3, Wiremod any custom gmod addons you add to. Before and After SVN Update.


[SIZE="5"]Note:[/SIZE] I had this problem before. I just deleted any useless junk files from my computer. Also any gmod addons you don't really use. Then I lastly Disk Defrag using Auslogics Disk Defrag and I'm back to gaming :P
