System specs would help tremendously here.

My two cents.

OP's system spec listing...

System Manufacturer/Model Number have several computers, not just one
OS Windows 7 64-bit

Sorry, just trying to help.
Thanks Sygnus, honestly this same topic has come and gone so many times at the EVGA forum that I lost count. It's also been confirmed that the coils on the MB are responsible for making the noise although the power supply is the actual culprit. Although changing the MB has also fixed this problem on occasion. No system specs required for me to figure this one out LOL.

As you summized and suggested, the only fix seems to using a different or higher out power supply or changing out the MB. This has been confirmed to work quite a few times already.

Again agreed seen this problem many times.

Yeah, I know certain Corsair power supplies & Gigabye and Asus motherboards had issue co-existing together.

Hope he figures it out.

Thanks.

My hardware is now listed (well, everything but the disk drives and CD/DVD).

I did some more testing, and it seems that as soon as the video/graphics starts to get pushed, the noise shows up.

My friend Art, who assembled all the bits and pieces, feels that it's a top line power supply and it's unlikely that this could be the problem. So that moves it down on the list of possible causes.

CPU --- ??
CPU temp. --- readings stay within reason
Motherboard --- ??
Video Card --- already swapped for another
Fans --- all are turning OK,
Memory --- testing did not show any problems
BIOS --- upgraded to latest
OS --- up to date
Swap space --- ??
Power Supply --- ??

If a high pitch screech like this is caused by a problem, there should be some kind of program/software that can measure the appropriate things, and indicate what the problem is, right?

I just downloaded and ran "CPU-Z" which seems to analyze the whole computer. My friend Art suggested I do this, but I don't know enough to recognize anything that might be "wrong". I can copy over part (or all) of the results here, if that would help...

An even better utility seems to be "Speedfan"
Download SpeedFan - Access temperature sensor in your computer

I'm too sleepy to do much about this tonight; will continue tomorrow.

I haven't seen an answer to my question yet. maybe I missed it. But if you take the case side off, you should be able to listen to where the noise is coming from. That's the quickest, easiest way to tell where the problem is. If you put your ear right in the case, you'll know right away.

I will do that today. Makes perfect sense.

The sound is as loud as if the noise was coming from a speaker - it's much louder than all my fans, and the computer itself. You can hear it from the next room.

I have read all this and have a few things to say. I haven't seen the request from sygnus21 asking for all computer specs, which is much need information. Top notch power supply doesn't get the job done. I would recommend not unhooking cpu cooling fan for a hour. The sound is coming from the speakers can be caused by many of your internal computer components and also outside sources. I don't know how anybody can help you unless the information requested is given. We can all guess for the next decade. As far as I can tell we all just going in circles. You have to help us help you.

He didn't say the sound was coming "from" the speakers, he said....

The statement has slightly different meaning, but... and you are correct about the souce being anything. I would also add that...

"If" there is sound coming from the speakers, that sounds like electrical noise, which can come from the motherboard, soundcard or any other electrical component. A bit confusing now

Question to the OP... is this a squealing noise? Can you explain it? Thanks.

I'm getting a high pitch sound coming through my Razer Tiamat 7.1 Headsets. The sound does lower as I lower the main volume, but then I can't hear anything else. Currently, I'm plugged into the rear USB ports and I tried switching to different USBs, but nothing changes.

High pitch sound coming from computer.
There's this high pitch sound coming from my computer. You can hear it if you're within like 6 or 7 feet. I think it's coming from the cooling fan. The weird thing I noticed is that the sound goes away if my ethernet cable is not plugged in. Any ideas how to fix it?
