I bought the MSI Z170A Gaming M5 Mobo back in February. It takes 90+ seconds to boot up into the screen that says "hit f11 to enter bios" and now I'm seeing it say my CPU clock speed is only .80GHZ when I'm on a 6600k. I noticed the extremely slow clock speed issue when I reinstalled windows and I tried to play games that I could get 150FPS on ultra, and I'd get 40 on minimum.
