GMOD crashing

my friend’s gmod is crashing randomly…
he has tried reinstalling gmod… he never had a problem until the last few updates
Win7 x64
4850 X2
4gb ddr3-1600 ram

Halp, I don’t want my favourite admin to leave my community because of gmod crashes :crying:

don’t drive under the influence

Most likely a broken addon. (I’m assuming that he reinstalled all his addons after the uninstallation.)
