how to disable nouveau module totally?

Hi,

I upgraded my system from squeeze to wheezy, but now no desktop
environment is displayed. I tried to install nvidia's driver, but
cannot disable the nouveau module. I tried everything list
here:http://www.pimp-my-rig.com/2012/01/unload-nouveau-install-nvidia-driver.html.

Now what should I do?
