High pitched whine? Overclocking RAM?

[Macamoo]

Ok, i have just built a new computer. I installed windows 7 and all the drivers and everything and when i plugged in my speakers they worked fine. After a couple hours i noticed that ONLY when my speakers are ON they emit a very high pitched whine. Whats also very odd about this whine is it changes volume and pitch when ever i do things on my computer. For instance when i open and close programs or a i play a high res video game. Also the weirdest part is when i watch youtube videos, it will change accordingly with the video. It's very strange and i haven't found anyways to stop it. i even took any power cords away from my mobo and processor in case they were interfering. Any help would be great, thanks.

You are always taking a chance when you buy an "open box" component. You may have to install a cheap sound card and disable the onboard audio.
