High pitch whine/noise emiiting from CPU area

October 20, 2010 at 14:26:58
Specs: Windows 7 64 bit

I recently changed my motherboard because of a host of problems know that i changed it i am getting a high pitch whine emitting from my CPU area when the machine is under load booting from BIOS is fine but as soon as windows loads up it kicks off

Momentarily it was much worse but after updating my BIOS and disabling CPU stream it has gradually reduced but still there

I am running the following:

AMD Athlon 64 X2 6000+
2GB Corsair XMS2 and 2GB Samsung RAM
M4A78-HTPC Motherboard
500GB Samsung HD and 250 GB Seagate HD

Also the following below will show why i have eliminated to around the CPU area

- Tried 3 Different PSU's namely antec and coolermaster
- Tried 2 set of RAM Sticks
- Disabled Hard Drives - Defragmented them
- Even took the CPU cooler off for a moment
- Booted PC up with minimal power input i.e. PSU, one HDD, and CPU Cooler
- Changed IDE cables
- Disabled every fan
- Took all the components apart within my case and laid them out separately and found that the noise was emitting from the CPU socket area
- Tried connecting my old MB with CPU connecting etc and there was no squeal

It seems I might need to replace the mobo but after updating the BIOS it seems to have subsided so i am thinking maybe manually changing the voltage or something

I'll never understand some people's troubleshooting methods.

Get yourself a piece of plastic tubing 2-3 ft long & use it as a makeshift stethoscope....hold one end up to your ear & probe around with the other end until you pinpoint the source of the noise.

I came across this method, but i am certain the noise is emitting from the CPU socket area even without the heat sink and CPU fan it still made the noise as soon it started loading Windows

With the bios update the noise has considerably dampened but still noticeable when there is any CPU/ hdd activity or browsing web pages.

my troubleshooting methods were based on previous replies i.e. might be hdd or psu or cpu fans etc so the above was to eliminate any other possibilities.

don't be jumping to conclusions yet...

it could be the voltage regulators for the cpu making the noise. i dealt with a motherboard once that was producing a strange high-pitched noise once, and it turned out that one of the voltage regulators was failing.

the idea with the tubing might be worth trying....

I'm back! (from a looooong time ago)

I understand the tubing idea but i am certain the noise is coming from the motherboard around the CPU area either as you stated could be a capicator problem or just wondering if i tweak with the voltage settings will it go away..

I have a PC with Giga945P-s3 dual booting XP / Vista.
It emitted a high-pitched sound which verged on the unbearable to people with normal high-range hearing.
After many hours googling sites, where most advice blamed power supplies,
or settings in BIOS (LLC, C1E, C3/C6/C7 Support, CPU EIST) none of which made sense to me.
The noise ceased when I set BIOS to "Load Optimised Defaults".
This PC was 2nd hand, so maybe some previous owner had been tweaking the BIOS settings.
Hope this helps.

@ x2dazee... did you ever solve the issue? I've got the exact same problem, and it's driving me insane...

yeah, passed it back to the manufacturer and got a replacement. I believe it was a capacitor problem but can't say for certain as it got shipped to Germany and didn't recieve a resolution etc.

I have the exact same problem, just switched out my motherboard and it wont stop. @evancipation if you find a solution I'd love to hear it
