Windows 10: Getting Random BSODs

My PC has been BSOD the past week. Trying to figure out what's going on, it ran fine when I did the upgrade for a month (New mobo, processor, and ram). I did a clean install of Windows 10 after I installed the new parts.

-Windows 10 1903 (OS Build 18362.535)
-AMD Ryzen 2700X (Not overclocked)
-RAM 32GB of this (Total 4 sticks) G.Skill Ripjaws V 16GB 2 x 8GB DDR4-3200 - Micro Center
-Motherboard ASUS ROG STRIX B450F GAMNG ATX

-Troubleshooting (Have all Windows updates, all updated drivers, reinstalled CPU drivers, up to date Bios drivers)
-BSOD is random and I get different errors such as:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (What failed: afd.sys)
SYSTEM_SERVICE_EXCEPTION
DRIVER_PORTION_MUST_BE_NONPAGED
KERNEL_SECURITY_CHECK_FAILURE

I found this thread Random BSODs - UNEXPECTED_KERNEL_MODE_TRAP afd.sys so I did the steps outlined by @zbook and pasted them below

It ran fine for a month. Now just get random BSOD randomly (Chrome, gaming, etc).

Any ideas would be much much appreciated!

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

Sorry, Bitdefender is a problem: BSOD BAD_POOL_HEADER - mwac.sys - Malwarebytes Anti-Malware Help - Malwarebytes Forums

 

Random BSODs "Bad_Pool_Caller"


This BSOD happens anywhere, irrespective of BitDefender. It takes place even when the antivirus is MSE in case of Windows 7. The most common cause is an expired trial or a cracked installation. Some examples:

• Norton: Windows 7 Random bsod caused by tcpip.sys - Windows 7 Help Forums
• MBAM only: Epic BSOD error appears just after few seconds from boot Solved - Windows 7 Help Forums
• McAfee: BSOD on Internet Related Programs (tcpip.sys) - Windows 7 Help Forums
• Avast: Bad Pool Header 0x00000019 at random times - Windows 7 Help Forums
• Avira: BSOD randomly Crashes my Laptop and freezes at Memory dump 100 - Windows 7 Help Forums
• Crack: BSOD every 6 minutes, also recent freezes - Windows 7 Help Forums

We are on our way of troubleshooting. If the uninstallation and reinstallation does not work, we will take the next step.

I, in general, know what I am doing and what I am suggesting. If I feel that I am unable to control the issue, I will definitely ask for help.
