high frequency buzzing/ whining noise in the background of my PC

Hi Forum,

I'm Experiancing a wierd high frequency buzzing/ whining noise in the background of my PC, Speakers, Headphones

1. If I turn the speaker volume off or lower volume I can still hear the noise
2. When using Headphones the noise is much more noticable
3. Happens only when PC is under stress ex. Loading times for games, playing games
- Volume of noise changes depending on stress level high FPS and intense loading produce higher volume than simple tasks
- Can't hear the noise under normal PC operations ex. web browsing, watching a HD movie
4. Was quite a bit louder when PC was overclocked to 4.4ghz but when I return to default it is still noticeable
-Used Automatic Overclocking (AI Suite II - Auto Tuning - Fast)
5. When I open case to locate noise it seems to be coming from GPU but with all the fans running it's hard to pin point location

Any assistance would be greatly appreciated and if more information is needed I will gladly dig it up. Also If there a clear upgrades/improvements I should make that also would be much help.

Hello !

My first guess would be your PSU. What model is it ? If you're close to its maximal power output, it might explain the sound.
That would also explain why the sound was more noticeable when you overclocked your PC : it drew more power.

I hope this helped,

That pretty much confirms the source of your problem I think...I've never even heard of that PSU brand.

The best 2 PSU manufacturers out there are Antec and Corsair. In my opinion, Corsair is better, but they are also somewhat more expansive.

Also, are you planning on doing SLI/3-way SLI or stay with a single video card ? Also, what's your budget ?

If you stay with a single GTX 570, I'd go with a 750w.

If you want to do SLI, go with a 850w.

If you want to do 3-way SLI 1000w or higher.

Good shopping ! :-)

Thanks so much,

your service goes above and beyond.

Last question (Hopefully), If I were to go SLI can i use any model of the GTX 570.
Currently have: EVGA GeForce GTX 570 Superclocked.
Do I have to buy another one of those or can I use the slightly faster EVGA GeForce GTX 570 Classified.
or the ASUS
ENGTX570 DCII/2DIS/1280MD5 or ENGTX570/2DI/1280MD5

Again thanks for all your help and information

Yes. As long as the GPU is a GTX570, SLI will work.

You can buy any GTX 570 you like. However, I'd stick to the same model for the following reasons :
#1 You already know how much noise it makes. A different card might be louder than the model you have.
#2 In SLI, both cards must have the same amount of memory and the same memory density.

Since an update in the drivers in 2010 I think, cards in SLI don't need to be synced to work together. Meaning that you can have different clock speeds and memory speed.
