I built a new pc(, tell me if u need specs) and (64- bit) system says I'm the administrator but i can't make any changes to windows firewall, i can't activate or disable norton internet security and i can't change my account back to a regular one. Also (this hasn't got to do with the admin thing) 4 driver updates: Realtek High Definition Audio Driver, Intel Rapid Storage Technology, Intel Management Engine Interface and Intel USB 3.0 eXtensible Host Controller Driver can't be installed. neither can i play bf3 i still need to test other games because punkbuster can't be installed (also not manually) and every loud sound becomes a loud prrrrrrrrrrr. I'm completely depressed pls help
