So I built my second computer and everything was working great except for one issue. Anytime I moved my mouse I would get a faint electronic noise coming from my speakers/headphones. If I opened a window or scrolled up or down the noise would be a little louder and I could hear each little movement of the mouse. This would happen from every single 3.5mm audio port that I have, BUT not on HDMI. Now I have searched the web over and looked at pretty much all the topics relating to this, with no solution. Here is what I've I've done to test each component to see what is causing this, and it's leading me to think it's the CPU.
Swapped Hard drives, Graphics cards, Power supplies, mouse/keyboard, tried on board graphics (a-10 processor), different ram. Most recently I returned the motherboard for a new one, and the problem is still there. I have the computer hooked up to a power strip, and my old computer works fine on the same power cord and mouse/keyboard/monitor, so it can't be a ground isolation loop. This is leading me to think its ether a grounding problem on my new case, or the CPU.
I should also mention that when I start up that computer, and have headphones on, everything is fine until right after the windows 7 animation stops playing, then it sounds like someone turned on a amp or something and you can hear that there is power running through the line. That's not really a problem as the noise is minimal, but when I move my mouse or do any action on the computer, I hear the electronic noise with each movement.
CPU - AMD A10-5800K APU 3.8Ghz
Motherboard - FM2A75 PRO4-M
Graphics - Sapphire HD 6870
RAM - Kingston HyperX Genesis 4 GB 1866MHz
Hard Drive - Samsung 840 Series 120GB SATA III
PSU - CORSAIR Builder Series CX430
