When I used * on an IBM PIII 600 (6565-85U) it also made a nice noise. I 
switched to a dell poweredge and it's gone. It seems to be related to the 
power supply. I'd try adding sime decent size capacitors (5000 u+) to 5 and 
12V, if I had the time to mess with it. Check to see if it is certified for 
home use which is harder than office.
