strange noise when scrolling

[MikeF98765]

ok so in both my dads desktop and my new laptop, i get this strange almost clicking noise when i scroll a window. It happens when i use the mouse scroll button, when i drag the bar,or when i middle click and drag that around. When ever a window scrolls around i can hear a noise come form tthe computer. Not even from the speakers, the actual case. Both computesr happen to be IBMs. Anyone ever heard of htis before?

yeah I had the same thing happen to me in my old Gateway Celeron system. I am pretty sure that it is the hard drive making the noise. like it is tryin to keep up or something.
