After putting the card in place and pushing it down, I screwed it in to stabilize it. Windows 2000 installed the drivers for me, and all was good. If Windows does not have drivers for your card, it should prompt you for drivers. If you don't have a manual, just browse through the CD or floppy that was hopefully included with your hardware for the drivers. The biggest recommendation I can give if you're doing it for the first time is move slowly, and don't be afraid to give the card some force when trying to put it into its slot.
Some people are scared they'll break the card or something.
On the next page I'll cover the installation of some specific parts.
