High-pitch sound coming from computer

  1. I know there's a lot of posts on this topic already but I really just need to ask :x

    Only 2 days ago my computer started making a high pitch sound on
    very random occassions (sometimes when I am using digital art programs)
    and I can't seem to figure out what's wrong. My little brother has been whining
    and my dad can't seem to hear it D:

    I read some forum posts about it here and there.. most of them say it's a problem
    with either the dirty fans, HD, vid card/montior, or PSU? I cleaned out my computer
    so the dirty fan option is out...and I'm positive it's not my monitor because the
    sound is clearly coming from the computer..

    Problem is I don't know how to tell if it's the vid card, HD or PSU :(
    Help would be appreciated :)

    Oh if it helps, this started happening recently after I tried to transfer my data
    from my old HD to a new one. Might have something to do with that?

    Really high pitch, noise is most likely electronic. There are some choke coils on most mobos and in the PSU. The PSU is at the back top of your machine. Put your ear next to it and listen if sound is coming from there.

    Kirock is correct,its somewhere in your PSU.

    sounds like a dying PSU,one of your PSU's component is already dead & the resistor next to that component is now being cooked by excessive amounts of electricity.Usually, the resistor gets hot,if it exceeds the percent of the rated value or tolerance,and makes a strange high-pitched squeal.
