K7SOM+ sound issue

[AMDman]

I just bought a K7SOM+ for my friend. I've installed XP SP1 and all the driver. It has 128 MB DDR. No trouble at first, but when she plays Winamp, the computer restarted after a few minutes. Sometimes it restarted just before it enter the desktop (when the opening sound played). I've tried the latest driver (well, the latest driver made on 2002), I'm pretty sure it's because the sound.

Any idea? Please help.

Begin with disabling the sound (should be an option in the BIOS) and see if that really solves the issues.
