Trying to install software (nvidia drivers)

[Chrisss]

OK, I'm using Fedora Core 5, and I'm trying to install the Nvidia drivers. I downloaded the setup file from www.nvidia.com into my home directory and ran it, and it says I need to be logged in as the root. So I type 'su -' into the terminal and then try and run the file again, to which it says it can't find it, presumably because I'm no longer in the route.

How can I log in as the root and still run files from my home directory?

Thanks

What do you type into the terminal to 'cd to something'
