I am building my new PC, MB:ASUS Maximus XI Hero, CPU, 9900K, VGA card: MSI Seahawk 2080, RAM, G.skill F4-3200C16Q-32GTZR. after checked all power supply was correct, I started the 1st boot, but the boot stopped when one continuous beep followed by 3 short beeps, the Q-code was D6, and then one continuous beep followed by 4 short beep, Q-code was A2. I tried reload CMOS, 1 ram per time and change the position of RAM. remove the VGA card. but the boot stopped at the same time. why this happened? Is this the problem of the VGA card or the MB? Thanks
