Clear CMOS is often not enough.
Turn the system off. Switch the PSU off on the back of the PSU.
Remove the CMOS battery for five minutes. That may require removing the graphics card on some motherboards. While the CMOS battery is out of the motherboard, press the case power button continuously for 30 seconds.
Remove the memory from the motherboard. Reinstall the CMOS battery. Flip the switch back on, on the back of the power supply. Turn the power on and let it power up until you see or hear an error code indicating no memory is present.
Press the power button until the system shuts down. Flip the switch back off on the back of the power supply. Reinstall the memory. Flip the PSU back on and power up. Allow the system to "boot loop" in order to train the memory again. It may take as long as three tries.
See if the system will POST. If it will and you can get back into the BIOS, then do so and enable the memory D.O.C.P profile in the BIOS. Save settings and exit.
See if it will boot to Windows now. If it won't, then you may need to enter Windows in safe mode and undo the changes you made to the memory configuration in Ryzen master. In the future, do not EVER make overclocking changes to the CPU or memory using Ryzen master OR ANY OTHER SOFTWARE from within Windows. ALWAYS configure overclocking settings from within the BIOS.
If you cannot even get into Windows using safe mode, then it may be necessary, unfortunately, to do a clean install of Windows and hopefully you already had anything important backed up to another location.
