troubleshooting sound card problem after installing windows Xp professional SP2

I have recently installed a fresh copy of windows xp professional SP2 in my pc. After installation completed I found that my pc's sound system is not working, As it could not find the sound card. But I have a build-in sound card in my intel motherboard.

I checked Control Panel > Sounds and Audio Devices and found that there has been written
"no audio device" and other options in the window are disabled .

Then I checked Device Manager and here I found that every option under "Video And Game Controllers" is ok.
I started googling and found out the following website from where I got help for fixing this.

This is all I have done.

1. Download PC Wiizard from
http://www.cpuid.com/pcwizard.php

This will give the all information about system's hardware.
Note the description of Mainboard and chipset.
For my case,
Intel Mainboard : Intel D945GCNL
Chipset : Intel i945G/GZ

2. download and install Intel® Chipset Software Installation Utility for the chipset. Reboot the system.
I have found my one from

http://www.intel.com/support/chipsets/sb/CS-020683.htm

3. download and install the audio driver for the Intel Mainboard(Desktop board) of the system.

Done!

All these should make the sound card working again.
