Garrys Mod RP Crash

Hello,

My friend stumbled upon a problem. Whenever he joins a RP server and tries to do /me’s, talk, whisper, yell, any IC thingy, his Garrys Mod freezes and he has to CTRL+ALT+DELETE to close it.

He reinstalled, deleted his cache files, deleted his LUA files and everything, still doesnt work.

Help?

could it have anything to do with his system specifications?

Unlikely, but that’s all I got
