Yesterday I just built my new gaming rig. Everything seems to work fine, but when I plugged in my speakers, I get this faint, high-pitched screeching sound coming from the speakers and I don't know why.

First, my specs:

Windows 7 Ultimate x64
Gigabyte GA-990FX-UD3 (rev 3.0)
AMD Fx-8350 CPU
AMD HD 7950 GPU
No onboard audio
Now, the facts:

- Other audio works perfectly fine. I can listen to music and everything, but the screeching is still there, just not noticeable.

- The screeching problems began before I installed any audio drivers and they persist after getting the latest drivers.

- I've tried plugging the speakers into different outlets and such, no luck.

- I don't hear any screeching when listening with headphones.

- There's no screeching at the BIOS screen, it starts when the system starts to boot into Windows.

- Onboard audio drivers are from VIA.

- These are pretty old speakers (maybe around 10 years old) but I've never had a problem with them on my old computer (which was bought around 2007-ish)

- For some reason, the screeching gets louder when I use my mouse wheel which is plugged in via USB.

- I've tried uninstalling the software that came with the mobo, e.g. EasyTune6 and so on.

It's a small but maddening problem. Please help me dear experts!

Edit: Plugged the speakers into my laptop. No problems.

Update: The interference gets worse whenever I'm doing anything graphics intensive - e.g. games, Furmark

I think this happens with the CPU as well but to a lesser degree than the GPU.

I tested the speakers by plugging them into a different computer. No problems.
I tested the new computer by plugging in a different set of speakers. Also no problems.
Grrr.

:( i have this problem to usually its caused by a Driver problem Could also be a driver error with your mother board. Its nothing to worry about its just annoying to hear I would try to look up the latest sound drivers for your computer and make sure you have the everything up to date.. Also really weird but on one of my old computers windows update was messing with my sound causing that noise after i disabled windows updates it stopped. The only problem with that is i have to manually update windows xD. I do that now anyways but meh i got used to it.
