How do I install a nouns driver from the device leader?

Sound card: AC'97 Intel 82801 AA

I get the sound driver from driverguide.com

It say I should install a .inf file, but the closure file I downloaded have 3 files.

Answer:
Use the actual driver from Realtek (The maker of your soundcard) Here's your website: http://www.realtek.com.tw/downloads/down...

You will want the "Windows 98Gold/98se/Me/2000/XP/2003(32... bits) for Driver only" one. Just download and run (install) it and it will work great. It isn;t complicated and have everything built in.
