Updating your bios might fix this. So if you do not unplug and replug it doesnot start at all?

i updated bios from AO4 version to A07

What happens if you do not unplug and replug the power cord?

Is XMP enabled on your bios?

When did the problem start? Any change in hardware, or software? Try resetting the bios and setting the ram frequency and timings manually.
