Does it crash after you play on a specific server or load a specific mod ?

kk : I never load mods or something so that's not it.
No, there is no specific pose for the crash, sometimes it even happens in the menu, or in single player
And reinstalling didn't work

I got a 2 gb RAM
Nvidea 7600
Windows XP Pack 2

Ok.
Does the 'not responding appears suddently on the title of the window and Toribash freezes ?

Can you give the exact text that you see ?
A screenshot of the message / window would be best.

Thanks.

Sry for the dutch being, but that's the error i recieve
