Downgraded from windows 8 pro and I have major problems

Thanx all guys, the problem was in the swsetup sources norton 360 removed some files so I couldn't install drivers software correctly. Had to download them all again from scratch.

Over three years here based on problems seen we've recommended to replace Norton with preferred Microsoft Security Essentials countless times and never had a single complaint.

There are not any files in swsetup, that Norton would remove.

I had a virus in my portable hdd that affected ecerything so I think that was it after nortin 360 ran a full acan it removed threats
