Pc not booting after win update x470 taichi

HI,I'm on windows 10.Yesterday after a cumulative windows update, the pc required a restart, i was still on build 1809. From that time the pc is not booting anymore with a 0d or 0b error on the motherboard, sometimes 3 sounds come out from it. i had not the time to check yet because it happened this morning, and had to get to workplace, using work pc to write. Apparently was all good: fans spinning, lights on, there was electricity. But is like this electricity can't go to the mouse, keyboard and monitor, they not power on. Anyone experienced this unpleasent event and how to solve it? Can really a software update not involwing drivers or firmwares break a pc so badly? what the hell! thanks for the help you will give me.

But until yesterday all was good, until i didn't press restart and update...
anyway the ram is stock and i adeed my pc specs in signature

remove your windows drive and if it boots without beeping then you are right

either set a higher ram voltage or lower the ram frequency

well i managed to boot the pc via cmos reset button...when i did again my settings it didn't boot again. So i reset it again, it booted and tried to leave PBO auto, not enabled as it used to be, and now boots everytime. SO YOU ASROCK TECHNICIANS THAT MADE THIS BIOS, IT WAS SUPPOSED TO FIX PBO, it worked very well so far, BUT HOW THE HELL NOW THIS SETTING DOESN'T ALLOW MY PC TO BOOT???? HOW IS THIS EVEN POSSIBLE???? I think the bios is bugged, or bugs after some uses, i don't know, is for asrock to find out.

And why before as it was PBO ENABLED worked, and now i have to increase voltage to make it boot with PBO ENABLED? this doesn't make any sense! anyway i don't know about this cpu voltage offset, how to set it and what value set
