Hi, I just build a new rig few days ago. What im facing now is an issue that Q-code always showing 40 on my Asus Strix x399 E-Gaming motherboard. My last rig used to showed Q-code AO on the motherboard and i think that is normal but now im facing the Q-code 40 and sometimes Q-code AA. I do lot of research and many people saying it is normal and so on but I still want to know why it always showed Q-code 40. There must be something
