High pitch noise coming from speakers (headphones too)

I built my first computer back in November and after a month I noticed this high pitch sound coming from the speakers/headphones and it goes away when another noise comes through the speakers. So lets say I'm going into folders and every time I go into one windows makes a noise, but every so often when doing that I get the high pitched sound and it only goes away once another sound is played. It also seems to go away when I press one of my volume keys on my keyboard. Also if I hold a volume key down and change the volume from high to low I can hear the sounds but little beeps because it changes the volume.

I've searched everywhere and no one seems to have this problem. Also something else to note is that it's not the same sound every time, it will have different tones every time. And seeing as it's coming from the speakers (which are plugged into the back port) and from my headphones in the front audio port, I would think it would have something to do with the sound card with the motherboard. Maybe I need to update the sound driver (probably should have tried that first). So if someone could help me with this that would be great.

SPECS:
MOBO: Asrock FM2A75M-DGS
CPU: Amd A8-5600k (it's an apu so the graphics are integrated)
RAM: Corsair 1600 DDR3 (2 x 4gb)
PSU: Rosewill Fortress 550w
(Not even sure if my specs are needed for this)

Sorry for the long post. :p

It coud be something about the volume option on the keyboard if the keyboard is an old one that prefers USB 1.1 rather than USB 2.0 port.
Usually squealing or repeating noises implies your iphone or a microphone is too close, keep them at least 3 feet away from the speakers.

You could try using ferrite coils You loop the speaker wire around them to reduce the interference but you'd need a few of them and they don't always work as well as expected.

My keyboard is about 3-4 years old, I don't have an iphone (or a phone for that matter). It happens when the microphone is unplugged and far away also. And as I said it comes through the headphones when I have them plugged in so It couldn't be a speaker problem. I'm wondering if I should purchase a new sound card or maybe just update the sound driver (which I should do but for some reason I really don't want to).
