I have recently reformatted my computer for a range of reasons, and since reinstalling Windows XP Pro, have not had any sound. I have tried to install the Realtek AC'97 Audio driver because i vaguely remember it working before, but it did not work this time.

I have done the scan from this website and these are the results:

Any help would be greatly appreciated!

The best source for audio drivers is the computer manufacturers web site.

If the computer was custom built then go to the motherboard manufacturers web site.

Go to the driver download section and insert your model number. The drivers will be there.
