Question: What would cause a Sound Blaster Audigy card to screech when installed on a Biostar M7NCG 400 motherboard? I have a Biostar M&NCG 400 motherboard and on it I have a Sound Blaster Audigy sound card (PCI).  The sound card screeches fiercely during some games.  It does not screech when playing system sounds.  I thought it was a wire from the fan resting on the sound card and emitting static but that is not it.  Any ideas?
