When i install xp it installs all my drivers including the audio and network.

I disable the onboard audio because i use the soundblaster live! with 5.1 audio speakers.
I have not had a problem with this board but i am only using sdram
is your copy of windowsxp a copy?
if it is you should borow another copy and just use your original installation key.
you must have a bad xp disc.
this works flawless on my setup.
