I just started getting a code 99 with a long pause, then a short A2 sometimes and a short 9C on my Z97 gaming 7 board with Intel i5 processor. The board finishes booting after the codes. I also get a "USB device not recognized" after my windows 7 system finishes the boot. It has never done any of this before. Relatively new build. Any help? I reviewed some other posts but I not much of it helped.
