No POST after Bios update

Download and run memtest. Just to eliminate a memory problem.

You haven't said anything about the CPU temperature and the video card temperature while gaming. We have no idea about the PC case or the case fan configuration, or the CPU cooler you are using. Excessive temperatures in a video card causes problems, and with the CPU too. The fan speed reading when the PC freezes is just bad data coming into HWMonitor, or the program itself failing and displaying a bad fan speed reading. No PC fan can reach 60,000 RPM, and as you said you don't even hear them at their own maximum speed, so they really never changed speed. Since HWMonitor is showing a VCore of 2.8V, which is twice the 1.4V you see in HWiNFO, that means HWMonitor has not been updated to work with ASRock Ryzen boards, or at least the version you are using is not compatible with Ryzen systems. We saw the same doubled VCore reading in CPU-Z 1.79, now fixed in 1.79.1.

Default BIOS settings.

Cool 'n' Quite is enabled
AMD fTPM is disabled
SVM mode is disabled
C6 mode is enabled

Core VIDs are all 0.994V

That is the Vcore I listed, it fluctuates between 0.7V and 1.4V

I am using "AMD Ryzen Balanced" power plan, which came with the latest chipset drivers

My temperatures are 35C across the board while idle, and raise no higher than 45C when gaming. Using Ryzen's stock cooler.

Actually, CPU-z and HWMonitor were, corrected in newest versions, adding SoC and vCore together.
