Blue Screen of Death (BSOD) Posting Instructions
When posting a new crash dump, include all System File Collection and health reports. They contain valuable information that we can use to find the cause of the crashes.
Most of the time just the dump files are not enough information.
These two crashes are the same as the first two, indicating CPU.
Code:
Probably caused by : AuthenticAMD
WHEA_UNCORRECTABLE_ERROR (124)
A fatal hardware error has occurred. Parameter 1 identifies the type of error
source that reported the error. Parameter 2 holds the address of the
WHEA_ERROR_RECORD structure that describes the error conditon.
Arguments:
Arg1: 0000000000000000, Machine Check Exception
Arg2: fffffa8007e31028, Address of the WHEA_ERROR_RECORD structure.
Arg3: 00000000bc800800, High order 32-bits of the MCi_STATUS value.
Arg4: 0000000000010137, Low order 32-bits of the MCi_STATUS value.
IMAGE_NAME: AuthenticAMD
FAILURE_BUCKET_ID: X64_0x124_AuthenticAMD_PROCESSOR_CACHE
OCCT graphs:
Most of the frequency graphs aren't very steady, which is likely caused by the inconsistent voltage.
The voltage graphs are not near as smooth as they should be, with the exception of the +3.3v graph.
The CPU Vcore is very bad, when your system is at idle it is extremely bad.
Do you have Cool'n'Quiet enabled?
Your CPU frequency doesn't change but the voltage does try to change.
I wouldn't put any new components in this system, they may get damaged by the voltage fluctuations.
From this system's history, I would say the old PSU has probably damaged the motherboard and/or CPU. Other components may be damaged as well.
The only way to test this is to install another motherboard in your system and see if it's stable.
Another option is to put your CPU in another known good system and see if the OCCT graphs look the same.
You can make sure all the drivers are up to date and the BIOS is updated, but I don't think this will help, won't hurt to try.
