BSOD Random 0x000000BE nvlddmkm.sys

From the first snip you lowered the 'CPU Voltage Control' to 1.250v, this is why your system crashed.
Set it back to 'Normal'.
You set the 'CPU NB VID' to 1.1250v, should have been 1.250v.
You lowered the CPU voltage and the CPU/NB Voltage (CPU Integrated Memory Controller), which caused your system to crash.

I asked you to bump the 'CPU NB VID' to 1.250v, Not the 'CPU Voltage Control'.
If it's unstable then bump the 'CPU NB VID' to 1.30v.

Carefully follow these step:
After you set the 'CPU Voltage Control' back to 'Normal' change the following settings.
'DRAM Voltage Control' to 1.550v
'CPU NB VID' to 1.300v

Double check that you set these voltage controls correctly, lowering them will cause your system to crash, raising them too high can damage system components, CPU, RAM, and possibly the motherboard.

Your last crash from your zip file.

Code:

STOP 0x00000124: WHEA_UNCORRECTABLE_ERROR
Usual causes:  Hardware, Incompatibility, May be driver corruption
Probably caused by : AuthenticAMD
PROCESS_NAME:  chrome.exe
IMAGE_NAME:  AuthenticAMD
FAILURE_BUCKET_ID:  X64_0x124_AuthenticAMD_PROCESSOR_CACHE

This crash is blaming your CPU.
If you lowered the 'CPU Voltage Control' to 1.250v, this is why you got this BSoD stop code.

Let me know if you have any questions.

Can you confirm the voltage settings that are listed above?
'DRAM Voltage Control' to 1.550v
'CPU NB VID' to 1.300v

Did you re-install any of the programs that were requested to be un-installed?

Your last crash:

Code:

STOP 0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
Usual causes:  Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control,
Probably caused by : cdd.dll ( cdd!CDDPDEV::FlushGdiOutput+4b ) - Canonical Display Driver
EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.
READ_ADDRESS: GetPointerFromAddress: unable to read from fffff800034b8100
GetUlongFromAddress: unable to read from fffff800034b81c0
 ffffffffffffffff 
FAILURE_BUCKET_ID:  X64_0x7E_cdd!CDDPDEV::FlushGdiOutput+4b

Looks like a RAM error again.

If your DRAM voltage is at 1.550v now, then increase it to:
'DRAM Voltage Control' to 1.600v
Leave the 'CPU NB VID' at 1.300v

There is an indication that Steam and various games are causing the errors and likely the crashes.
Bump the DRAM voltage, and see if that helps.

That voltage is ok, AMD systems can take high voltages much better than Intel system.

Let us know if it is stable.

It's blaming the graphics driver.
Update the graphics driver, if it still crashes then install an older driver.
There is a possibility that this is caused by the graphics card, load new/old drivers to see if it stops.

Code:

STOP 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL

Hope it's stable now.

Let us know if you get any more crashes.
