    I just recently sent my imac (21.5", 1 year old) to the factory to have the lcd screen changed because i was getting black clouding on my screen and the disc tray changed, anyways I get my cpu back and all is well but now it is making a high pitched hummin noise constantly that it never made before. I mean I've been trying to ignore it but cmon it's annoying and the fact that it didn't do it before really pisses me off, i don't even have to be close to it i can hear it n e were in the room...Has n e one had this and it went away or what should i do...thanks alot:)

    Try adjusting your screen brightness and see if the sound changes. Many are complaining about this.
