Would it be 'feedback'?  the same as you get from a stereo system when the
speakers are too close?
Just a thought,

I put to together a system epox mobo kl133 750mhz everything ran ok I
delivered it and they called me with bad hum in the speakers.  The sound in
built into the mobo and I was using the drivers downloaded from epox.  I
made sure the speakers are not next to the monitor or electrical wiring I
rebooted the system using a boot disk  to dos and I still have this hum
when the speakers are turned up all of the way.  I even installed a new pci
sound card same problem.  Any and all ideas on how to proceed appreciated.
