I recently installed a case speaker on my motherboard and find that it clicks when the power is off. Not very loud, but never-the-less has me wondering why. Even does it when the vacation switch was flipped off. Sometimes after leaving it off it will go away.
Remove all the outside power devices and see if it stops, VGA/DVI cable, cat5 cable, ext speakers, see if it stops the clicking, anything USB that has a PS that could feed back
Thanks, Number13. When I simply switched off the power to my monitor (NEC 20wmgx2, connected via DVI on Gigabyte 8600GT) it stopped. Don't suppose you could explain what is going on could you? What is this feedback? And why does it happen?
