Tarmac! Hello again.
Disregard what Wulf said if you're using the onboard sound. (Sorry, Wulf!) But if you are, why the heck are you installing sound drivers, and what exactly are the sound drivers you're installing? Could they be clashing with the onboard sound function? Are these drivers for a redundant soundcard?
I have that very same board - it's a damn good board. I
was using the Creative SB Live Value! sound card, but uninstalled it when I was trying to solve another problem. I've been using the onboard sound ever since, having discovered that it is very good indeed. So no need to bother with a sound card. The onboard sound also works well for Aces High if you're using a headset with attached mike... So if you're still using a dedicated PCI soundcard, consider dumping it in favour of the onboard sound. Yes I know - onboard sound used to be crap, but this is Asus/Nforce we are talking about.
Not knowing what those "sound drivers" are that you've installed, my best guess is for you to reinstall the Nvidia drivers for the mobo. I'm using the 3.13 set, and didn't need to install any "sound drivers". The file name you're looking for is
nForce_3.13_WinXP2K_WHQL_english.exe - for W2K or WXP. You may already have that. If not, download it from the
Nvidia website.
Try that, and if it doesn't work, post back.
