I have a AX370 Gaming 5 board that has been running fine until today. I restarted the machine and it just remained in a boot loop getting to debug code 90 before restarting.
I've pulled but one stick or ram and tried it in all sockets, reseated CPU, cleared CMOS and replaced battery, unplugged all connections except power plugs and water pump. Nothing so far has worked.
