Hello a couple days ago I built my new pc. I got the 4790k and maximus hero 7. I left my old pc to my little brother and so I installed my copy of windows 8.1 on my Samsung 840 EVO and booted to desktop and I don't have network adapter drivers. I reinstalled windows and still no internet.. is it because I have to activate my copy of windows or could my Ethernet port be defective..
