strange arcing in iMac

the iMac g5 has a very strange arcing sound when I take a screen shot using command shift 3 or 4 while iTunes is running or preview is open is this a normal occurrence I sounds like eventually this is going to blowup does anyone else experience this? Scares the heck out of you if your volume is set loud. I think I have ignored this problem long enough, I have to make sure it is a problem before I contact Apple care.

it makes a 'camera' noise when you hit those keys, it should sound like your taking a picture

I have a funny feeling that is what he is hearing, but it really does sound like a camera click.

Yes It makes that noise also but it also sounds like sparking inside computer

mute or turn off all your speakers and try again, just to make sure that it is or isnt coming from the compy

thats just it It doesn't do it every time I will try and record the noise and link it on here give me a few

Like Coach suggested, see if you can get that noise with the volume mutted. If not, it has to be coming from the speakers.

it figures, I can not duplicate it, as soon as I stop trying, it will startup again you watch..errrrr!
