P6T squeezing noise when browsing

[pp1111]

When I browsing , scroll the mouse of the web page or in the main screen (before start) of Video Card Stability Test program http://freestone-group.com/video-card-stability-test.htm , my power supply will make squeezing noise.
When I start video testing, noise gone. It squeeze also whwn HDD running loading things.
I did tried different brand power supply, different video card, no help.

Does anyone got this problem?
Do you think is the motherboard?

i7 920, P6T, HX620, 1333DDR3 12GB, GTS 250, WD Black 640GB, P182

Got a P6T also and I get a similar squeezing sound from my USB headphones. I used to get them from the P6T's sound chip too when I had speakers plugged into that but after I installed newer drivers the squeezing sound was gone. Still get it from the USB headphones though. And it's not just the squeezing sound. When I do nothing I can hear a scratching kind of sound and when theres a flash animation or a flash banner playing on a website the scratching sound becomes louder.

It's definately something to do with this PC - possibly the mobo - because the headphones work fine with my old PC.

Does your sound come directly from the mobo or does it stop when you turn your speakers off?

I don't get this with my P6T Deluxe v2 but I did used to get it with an old PC. I never found out what the problem was but it had nothing to do with the speakers or sound card - scrolling the mouse wheel made a squealing sound come from either the PSU or a capacitor on the motherboard or something. :/

It actually from the power supply for sure but I can heard from the MB too around the videocard area.
My speaker is fine.
Have you try that Video Card Stability Test program and see?
In my case, when I load that on the menu scrren, it create the loudest noise and steady.
Yours from speaker? Have you take a closer hear from thr back of your PS?

That's what I found, too.
It's from the PS mainly but just surprise me changing PS won't help. so I guess must be MB, may be I should get your Deluxe model or other brand

I also have the P6T (vanilla) and had the same problem. I'd get these high pitched buzzing noises coming from the VRM area of the motherboard when the CPU was under a sustained full load. I installed the latest BIOS update and I only ever hear a slight 'squeak' from it every now and again.

I installed the latest bio too. My case is it squeeze under light load but not high

happened to me a few years ago, turned out to be a short in the case. remove your motherboard from the case put it on a static resistant and non conductive surface and try it out.
