Do you have a clean install of Win XP ? First try to clean install your pc and look on Netsuo's website for needed software/plugins/drivers. I never had problems of that kind, same MB, but it could be a combination of installed software or drivers.
Read the faq's here and on Netsuo's site, could be something you didn't try or think of. In fact your question is really hard to reply to because every system is different though the hardware can be the same.
