[Wine] Counter - Strike with Steam random Freeze, have to shut down

[Chris .]

Hey ! 
So i recently wanted to start playing CS again, i have the cd, installed it on steam and so on.
I think i have the latest version of Wine.
Anyway, the first times it worked fine, but now i get to play like 20 seconds(sometimes even 10-20 minutes), if lucky, and it just freezes and i can't do anything so i have to hold the power button for the laptop to shut down.(or do the alt+SysRq
reisub thing)
What can i do to fix it?
Oh, and also, i don't have any sound while playing.
I have Ubuntu 11.10
Thanks ahead!   :)
