Default CPU Idle Buzzing Sound

This is a weird one guys...

I JUST installed a brand new Asus K8N (Ai Series) motherboard with a AMD Athlon 3200+ processor.

I installed Windows XP with no problems. BUT... as soon as Windows XP loaded (as in started loading... just after the Windows XP Boot screen) a constant buzzing sound came from the CPU... not the hard drive... the CPU.

After listening around as I tinkered within Windows XP, I noticed the buzzing skips in frequency as the CPU usage inscreases. In short, if the CPU isn't working (0% usage), the buzzing is solid and constant. If the CPU is around 50% usage, the buzzing is a quick-skipping-buzz. If the CPU is at 100% usage, the buzzing is totally gone.

It's NOT the fan. I lightly pressed on the fan as the computer was on just to make sure the thing wasn't wiggling, thus causing the sound.

After some research, I guess Linux systems had a "Make CPU Idle calls when idle" kernel option... but Windows XP? I think not!

What the heck is this sound?

I've seen a few other people with AMD Athlon's complaining about similar sounds. Let's clear this up once and for all!

Thanks in advance for any help... I'm going to go crazy soon if I don't figure this out!

What would you recommend? Changing the power... but how? What should I change and how much?

Thanks!

I've never even eard of that problem before, thats crazy. Try a different power supply. If that does not work, then go to extremes and switch the processor out with another one... If you can. If that is the problem, then get a new processor if it bugs you that much. If there seems as though there is no problem with it, other than the obvious noise, and you can live with the noise, then deal with it. Other than that, it's all the advice I can give you.

I seem to have having a simulare problem, but the buzz seems to be in time with the harddrive usage.

This is on a customer's computers, the spec is as follows ;-
Intel Pentium 4 3.4Ghz LGA775 90NM CPU
Gigabyte GA-8ANXP-D Motherboard
2x 512MB DDR2 PC4300 533MHZ
Seagate 160 Gb SATA Hard drive
Benq 16x DVD with Software
Pioneer DVD-RW
Gigabyte¬ģ nVidia Geforce 6600GT + PCI-E 16X 128MB DDR3, + PCI-E 16X 128MB DDR3, 128 Bit / TV-Out + DVI / Direct X 9.0 + OpenGL + VTUNER II VIDEO CARD
interneral 56K NetComm Modem
Black Rolls Royce Case 450 Watt PSU LGA775 Power supply
USB Blue Tooth Adaptor (Upto 10Meters)



I am going to change the hard drive and then the PSU around and see what happens.

[EDIT] It was the PSU [/EDIT]

Actually I think that's your fan trying to keep up with your Processor. If the processor gets too warm (usage) then your fan will move faster to try and cool it down, again this is just a hunch but mine makes a really loud buzzing sound and it's my fan cooling down my CPU. Just something to think about.

No, it was actually the start up. And it was when I change the PSU over , the sound stopped.
