Ok, so my mobo blew out on me 2 weeks ago, I installed a temp mobo awaiting the replacement, now installed the replacement (same board as the 1st one) and Windows is saying it is not activated. I used the same commands that I did the first time around, which went with no problem. This is an Asus Sabertooth Z77 mobo on Win7 x64 Ultimate. Any help would be GREATLY appreciated. Thank you!!!
