Thank u for the reply .. I decided to exchange mother board ... I was moving the power connector and pluging it back into MB it seemed to resolve issue temporarily but same problem recurred after 3rd try. So I decided to exchange MB.. Will post outcome once new mb arrives.
Hello I changed mb , ram, and updated to latest bios but problem persists I even have usb 3 not working and my sound as well.. Don't know what to do ... Could it be my windows 8 or psu??
