Scrolling in IE pages - GPU making noise?

Hi all,

I wondered if the Tom's community could please kindly assist with a small matter :-)

Something inside my computer tower makes noise when I scroll up and down within an Internet Explorer window. I haven't been able to replicate the noise using other applications such as Firefox (browsing the same URL as IE) or MS Word etc. That said, sometimes I think I hear it in small burts when using other apps. Hard to know. It's quite a faint noise.

I think it's the GPU (where the sound is coming from) which is why I posted this in the ATI forum. It makes the noise whether or not the monitor is switched on or off. I would describe the noise as 'tinny' - though, I've never been good at describing things, I'm sorry!

Something I just noticed - if I scroll all the way to the end of the page, the noise stops (even if I keep rolling the scroll wheel).

Any ideas? I've installed the latest drivers from ATI.

I'm not too concerned but just stumped as to what's causing this symptom!!! It seems to come and go but it apparent more often than not. It happens whether I use the scroll wheel on the mouse, scroll wheel on keyboard or just scroll by dragging the scroll bar manually.

I don't have ANY speakers in this system. Not on-board, not external.

Any advice will be greatly appreciated :-)

Doak.
