I bought this new pc an acer aspire G3 - 605 Gaming PC from PC world only had it for 2 months and it started making a buzzing sound whenever I use the mouse or keyboard and I can here it when listening/watching media or playing games. It's fine when I'm not using them but still doing those stuff. It also goes away for a while if I plug the mouse into a different usb slot, as it really is mainly the mouse and I have tried other mice still same result. I would like some help please and if possible an answer put in simple terms.
