Static noise with new motherboard

[mart.pork]

Recently i bought new Mobo: Gigabyte Z370-p. After the first boot there was a static noise. When i move my mouse then i makes strange noise. Tried booting to BIOS, no static in there. There is static in my mic also. I tried all the tips, but nothing helped. Grounded pc, soundcard, new Psu, Other headphones.
