Hey guyz. I just finished building my own pc and I'm using the mobo asus max gene... however I notice from my cousins pc that their qcodes does not indicate any number or does not have anything on it while mines says A0... and also I just got back from the computer store and bought an hdd how do I add this hdd? I plug the hdd and its not showing when I click the my computer.. all it shows is the 120gb ssd I bought....
