I know that Linux users have problems with Ryzens freezing when idling and the fix is to disable global C states in the BIOS. AMD blames it on power supplies but any that claims to be Intel Haswell compatible should be able to output the low power the processor consumes at idle without shutting down.

We have been investigating the issue where systems are reportedly locking up when idling or running small workloads.
This issue is related to the power supply.
Most PC power supplies (PSUs) are designed to handle a wide range of power consumption from your PC components, but not all PSUs are created equal.
Because of this, there are some rare conditions where the power draw of an efficient PC does not meet the minimum power consumption requirements for one or more circuits inside some PSUs.
This scenario (called “minimal loading supply”) can cause such PSUs to output poor quality power, or shut off entirely. To prevent this issue from happening, it is important to ensure that the power supply supports 0A minimum load on the +12V circuit.
These PSUs became commonplace starting in 2013 for the Intel “Haswell” platform.
This specification can be found printed on the sticker affixed to most PSUs, or it may be available on the manufacturer’s website.
However, AMD understands that not everyone is in a position to replace their PSU with a contemporary 0A-rated unit.
To help with that, AMD is also developing a firmware workaround for these power supplies, and will make it available through motherboard partners as a BIOS update in the future.

After reading various forums, I saw that those who overclock the system have a stable system (most of them overclocking). Those users who are all standard have problems. I assume that the problem is in "AGESA", which is in every bios. It does not have the right standard CPU power settings. The power goes down to a lower critical level and the links between the CPU and the RAM or the PCI lines are lost. Two days ago, I turned off the "global C states control", and yesterday got a blue screen that pointed to the RAM problem (checked by memtest86, there are no problems). And before that, at first the image disappeared, during this GPU the cooler worked. That is, the link between the CPU and the GPU is lost, and power is supplied to the GPU. We have different chipsets, motherboard manufacturers, processor models, and the problems are very similar. Sorry for my english, I hope you all understand what I wrote
