A friend of mine in the UK is now getting a beep code from his ASUS PRIME A320M-K motherboard after installing a new Gigabyte GTX 1660 and a ARESGAME 650w power supply. He first installed the PSU and booted up the system with no problems whatsoever, it wasn't until he installed the 1660 into the computer did he hear the beep code and see no display during POST. The beep code was 1 long beep, 3 short beeps. I checked online for the error associated with the code for ASUS motherboards and for the most part, it signified a conventional RAM error, so I had him reseat the RAM, and even swapped the sticks position (not the slots). Same beep code, now I myself have no idea whats causing the beep code, even ideas?
