Random BSODs again. Removed all PCI cards, switched to on-board sound (VIA AC'97, latest drivers). Crashed in the middle of the night whilst burning a DVD with Nero and in the afternoon with iTunes playing for the 10th consecutive hour or so. I've ordered a new stick of RAM. Until then, could this be the sound driver? If so, does anyone know of a reliable driver for the onboard sound on VIA PM800 motherboards? Thanks.
