Windows 10: 3 different BSODs - could use some help determining root cause

This is a brand new Ryzen 3600 build. I've had a number of blue screen errors that I have resolved but there are a few I cannot seem to determine the issues on:


APC_INDEX_MISMATCH

This was probably caused by the following module: ntoskrnl.exe nt+0x3F5780
Bugcheck code: 0x1 0x7FFBF9B2C034, 0x0, 0xFFFF, 0xFFFFE30EA59E7B80


DPC_WATCHDOG_VIOLATION

This was probably caused by the following module: amdppm.sys amdppm+0x2ec7
Bugcheck code: 0x133 0x1, 0x1E00, 0xFFFFF800714FA320, 0x0


KERNEL_SECURITY_CHECK_FAILURE

This was probably caused by the following module: ntoskrnl.exe nt+0x3F5210
Bugcheck code: 0x139 0x3, 0xFFFFC70063867070, 0xFFFFC70063866FC8, 0x0


Steps I have tried:

• I've done a complete reinstall of Windows 10 to no avail
• Ran CHKDSK - no problems detected
• I've updated the bios to the newest version
• All software is at the latest version
• I ran memtest86 for 6 hours with no errors detected
• I've disabled nvidia sound devices as I believed they were interfering with realtek this seemingly has fixed some of the other bsods I had

Everything seems to think it is a software issue and I'd like to see if there's a common failure point here. Any help would definitely be appreciated.


I'll get a minidump added here shortly - don't want a BSOD hitting before I can post.

method to determine exactly what caused a particular update?

Two suggested articles from Microsoft....

• Fix Windows Update errors
• Troubleshoot problems updating Windows 10

Whether you find the exact cause will determine the level of troubleshooting you go through.

 

BSOD Hardware Caused???

they do weird things like that, which all seem like something else is failing.
One of the worst things to diagnose, they seem to only quit when they want to.

Memtest is a good next step, if you rule out RAM and Power Supply make sure you disconnect all unnecessary peripherals and try to start the system with as little hardware as possible, if it works then, you can narrow down the culprit by trial and error.

the follow was taken from some website:

It's very difficult to determine if a failure is caused by the CPU because many other components can cause the same symptom when they fail.

1. System fails to boot
2. System re-boots intermittently
3. General Protection Fault
4. Illegal Operation
5. Stop Error, or BSoD (Blue Screen OfDeath)

Actually, CPUs rarely fail, and about the only way to determine if the CPU is causing the failure is to swap it out with a known working CPU of the same type and speed. Since this is difficult, the best bet is to first rule out every other possibility.

Before suspecting the CPU, rule out all the possibilities listed below.

1. The Operating System
2. A peripheral port device
3. A bad memory module
4. The hard disk drive
5. The power supply
6. The motherboard

If you have ruled out out all the other possibilities, investigate the items listed below.

1. Overheating
2. A short circuit
3. ESD

 

BSOD Hardware Caused???

It is not overheating - CPU runs 60*C in games.
Short Circuit - EXTREAMLY UNLIKELY
