Normal, I thought my mobo had some kind of defect / issue just like you suspected. I had my case open last night cause I was installing my new ram cooler, I powered down my rig and the Republic Of Gamers logo in the middle of the board was pulsating and my power reset / buttons were lit up as well. I knew the pwr and reset buttons were supposed to be lit because my last ROG mobo did the same thing, but as far as the ROG logo fading in and out made me paranoid.
