The BIOS version was updated to 5.90 through the Ryzen 3 1200 processor.
On the motherboard AB350M-HDV with version 5.90, Rizen 5 3600 did not start up, although the Asrock website says that it supports BIOS version 5.90. The initial boot occurs, I can go into the BIOS and see what he sees the processor, but when the system boots, nothing happens endlessly twists the boot. What can you recommend? Is it really necessary to take a new motherboard or is there an option to somehow start this? Maybe I'm doing something wrong?
