(Not sure if this is right category) Its been about a month since i installed my MB and it has had a static noise pretty much since i got it and it has been getting to me lately...My board is the ASUS Z97-E, my CPU (which i believe is the cause) is the I7-4790k (Clock not touched) and my PSU is the Evga 500W...The noise gets worse when i play a heavy CPU game such as CS:GO, the pitch also seems to be slightly affected by my mouse as well, I am using on board audio (Realtek up to date), i am fairly certain that it isn't my HDD as when a game loads it doesn't change the sound at all...But I actually have no idea, anyone have a fix besides buying a new sound card? If any other details are needed just ask, any help is thanked.
