Question about Dell OPTIPLEX GX240 P4 1.7GHz 256MB 20GB DESKTOP (PCP417DELL)
The buzzing sound could be from what they call a Ground Loop.
This is cause by plugging in Hi Fi and computer devices etc. into different mains power sockets.
The way around this is to use a power board and connect all your devices into the power board and plug the power board into a single power socket.
