Odd computer buzz noise when scrolling, resizing windows

Hi, I have read a few posts around the net from other people with similar problems. No one seems to have a definite answer.

I am posting becaue I have noticed the same phenomen on both my home computer and office computer (totally different machines from different stores).

On my home computer, a
-Celeron D 2.53
-generic power supply (unknown wattage)
-80 Gb generic HD
-Asus P4SP-MX mainboard
it sounds as though the CPU Fan slows down for a slight moment when I start to scroll through a website or resize a window. Could doing such a simple task really drain so much power out of the system as to slow a fan?

On my office computer, a
-Sempron 2800+
-antec power supply (300W?)
-generic 80 GB HD
-Asus mainboard (don't know model)
there is a high-pitched whine that seems to come from the hard-drive when I scroll through a website or resize a window. Also, the HD LED seems to blink when I do this. This noise is most noticable when I am resizing a cropping window for a photograph in a photo editing program.

The noises don't really bother me, it's just incredibly puzzling, especially because both computers are fairly new.
If anyone has any idea please post!

onboard sound?

potentially -- any interference on motherbaord traces can affect unshielded sound traces....


an idea.

How much RAM, especially in the office system? Can you borrow a peripheral sound card and test it in all of the various PCI slots to see if the issue occurs there as well?

Dib blit acceleration can cause your graphics adapter's power supply components to produce subharmonics which cause LC components to sing and whine in the audible range.

The fan speed changing is due to loose regulation as the cpu idle commands go from high to low. It's nearly non existant on today's systems and was very noticeable in the days when 2K came out on ACPI systems for that very reason.

Would scaling back the video acceleration in Control Panel > Display Properties > Settings > Advanced > Troubleshooting be worth a try?

Yes this can be used to see if the graphics adapter is indeed the culprit. This will make the computer feel really sluggish, however especially when scrolling in web pages, etc!

Yes! You will get to see how it looks for me through RDP and a 1000 mS avg. connection. :|
