This isn't the clicking noise that most people seem to have a problem with- it doesn't happen when I move my mac, it doesn't come from the lefthand corner, etc. My noise is a series of 4 quick clicks that happens randomly as I'm using my Mac. Also, this noise can only be heard while the volume is on, so it's some sort of internal problem. Shutting off my computer doesn't work, and since that's pretty much my limit in terms of fixing tech problems, I'm at a loss. Does anyone know what this problem might be?
