Jbander :
The drivers that are in my "additional drivers" program don't work, I've tried them . It Freezes and it goes to black screen. I'm trying to solve this problem with other drivers.
But is the computer working now with just the generic drivers? Because if it works vanilla, just leave it that way. Generic drivers are usually fine for cards that age, and trying to install non-generic is usually not worth the headache. Occasionally the generic drivers are actually better then the N specific ones.
But if it does not work (and graphics drivers with Linux can be really "your mileage may vary"), I've had very good success installing N drivers from command line. Drop out of the desktop (ALT+F2), navigate to the / where your driver.run file is, and run the driver install from there.
Then restart X (sudo /etc/init.d/gdm restart, assuming you are using GNOME)
If the straight forward approach doesn't work there's still a lot of troubleshooting you can do, just head to google and start your research.
