My PC is making very strange noises all the time. anytime you do anything or the computer does anything you can hear an audio representation of it. anytime you press a key on the keyboard it makes a popping sound and the mouse makes a buzzing sound when you move it. Also anytime you scroll up or down in internet explorer it makes a funnny squeak, and any time the hard drive turns on or accesses data it buzzes. otherwise there is also a constant helicopter type click. I already tried istalling new drivers. Anybody have any ideas?

My system
black soyo micro atx case
a7n8x w/ xp2400 oc'd to 2600
radeon 8500le
SBlive value
512mb crucial ddr400
120Gig seagate barricuda
dvd rom, 52x cdrom, 48x sony burner
3.5" upfront audio and usb insert

Just a guess but it sounds like bad shielding on your speaker cables......picks up interference from all electical components.
