Gmod 10 crashes when joining a server

Hi,

Ehm,Like said in the title,my Garry’s Mod 10 crashes when I join a server.
He never did that before.
I tryed to reboot my PC and Steam with.

I cleaned Gmod like asked,and installed only 3 add-ons:

-PHX 3;
-Wiremod;
-Gmod Tower Pack.

My specs are:
Windows Vista Familial Edition 32 Bits
Intel® Pentium® Dual CPU T2390 @ 1.86GHz (2 CPUs), ~1.9GHz
2038MB RAM

Ehm,I believe I said all.

Thanks for future help.

Um, make sure you wait a while if it freezes in “Retrieving server info…” if this is your first server connect.
