This is a new one to me. Has any one ever come across the internal speaker playing "when the Saints go marching in" constantly. And when O/S boots up it continues with the O/S running at a 1/10th of normal speed. It is not a virus that Norton could find. The Mother board is a San Li i430TX-W977TF. The problem has been intermittant, occuring approx 8 times over a 3 year period. This latest occurence which I witnessed has yet again dissapeared on returning the machine to my workshop.
