Did you reboot?? Liam is right, please bottom post and trim off the 
cruft. Would you post the content of your /etc/X11/xorg.conf file? (at 
the bottom of your reply, naturally) It SHOULD have these lines in it:

Section "Device"
     Identifier     "Device0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
     BoardName      "GeForce 9400 GT"
EndSection

...The only difference should be the BoardName in your case. If you have 
display at all, and you have something else loading as Driver, other 
than nvidia, copy that file to something for a backup like 
xorg.conf.safebackup then edit xorg.conf and put nvidia inbetween the 
quotes. Reboot. If that blows up, you can use safe login or text-mode 
to copy the backup file back to xorg.conf.

Also, if you have builtin graghics on the MB and you're having problems 
with an addon nvidia graphic card, you may have to adjust a bios setting 
to chose between the two. My ASUS MB has a selection for that under 
Chipset/Internal graphics. YMMV, Ric
