Don't guess, take a look at /var/log/Xorg.0.log. When doing this, first
grep EE, IOW run

grep EE /var/log/Xorg.0.log

Seems to be the answer ;).

Modules have to fit to the kernel. You should run the NVIDIA *run thingy

I've got no time to search for you an English howto, sorry, on the quick
I only found a German howto:

this depends to the distro you're using.
