This is a fairly easily fixed problem.
You need to go to
the nForce drivers download page and download the
tar.gz file.
You then need to extract the file.
CD to the directory.
If you extracted it to /home/foo/nforce/ then, run the command
cd /home/foo/nforce/
and then run the commands
make
and
make install
Then, cd to the nvnet directory
cd ./nvnet
Then run the commands:
make
and then
make install
One of these won't do anything, but I don't remember which one, and my computer has been fried, so I can't run them. But it doesn't matter, it won't hurt anything - just run both of them. Then, reboot, and it should work just fine.
That's what I did, but I'm a Linux n00b, too,
but it should still work.
