Usb Speaker Noise!

[Alvize]

Hello, I'm having a problem with my Scarlett2i2 2nd gen usb soundcard. I have KRK 8's and my problem is : When i'm moving mouse or i have google chrome or DAW opened i have a clear humming noise and when i move my mouse it's a buzzing noise. I have tried to put it on my laptop and it worked perfectly! Only when im on PC it sucks!

Wndows 8.1
Intel i7 4790K
12 GB RAM

And its coming from right speaker only!

Things i've tried:
- Another usb port
- Moving mouse usb to another port
- All usb's out just soundacrd (still a noise)
- Tried different cable, but that was stupid because it works on laptop perfectly!
- Tried uninstalling from device manager and uninstalling drivers!
