Tru looking for an alternative site - i saw that Sapphire has alot of boards with that chipset. Just make sure you're installing the SB450 ati chipset driver (though maybe SB480 will work the same?) . I would try installing then in safe mode, but before i did any of that i would uninstall the sound drivers, then uninstall the ati drivers(without restaring), then boot down and boot into safe mode and install the ati chipset drivers, then the sound drivers after a reboot into regular XP mode. Past that i would try emailing Intel about it and see what they have to say.
