I updated my B450M Pro4 to 5.3 BIOS today (from 4.3). I get three beeps until I choose the correct XMP profile in the BIOS for my memory. However, I still get the three beeps when I exit out of the BIOS and when I attempt to restart the machine in Windows. Shutting down in Windows works and starting up also works. I Just get the three beeps when I restart in Windows or exit out of BIOS. I have DDR4 3200 Crucial Memory and it passes Memtest. I also pulled the battery out to reset CMOS but didn't seem to change anything. Should I try reflashing the BIOS again?
