Inconsistent BSOD on start up.

[Katnip]

Hello! First post here, so I hope that I don't do anything stupid.

Currently having problems with BSOD when I boot up my system. The thing that is frustrating is that it isn't consistent. It can be days without any issues, or it can happen multiple days in a row. And only when the system is being booted on, have never had it happen when the system gets to windows. Also, the BSOD never appears a second time after the PC resets.

The two error codes I have had are:

1 - System thread exception not handled.

2 - Kernel Security Check Failure.

I have included the DMP files in a zip attached to this post. One is the Kernel Security Check Failure, and the other is the latest System Thread Exception.

The system thread exception is the common one, what I normally get. The Kernel Security was new today. System also freezes during or just after the windows orbs are finished doing there thing with a black screen that doesn't let me do anything aside from hitting the restart button.

System is relatively new - having been completed in mid March.

System Specs -

Operating System - Windows 10 64 bit.
Motherboard - MSI MPG X570 Gaming Edge Wifi (Bios 7C37v17)
Processor - Ryzen 5 3500x
Memory - Corsair Vengeance RGB Pro 16 GB DDR4-3200 Memory
GPU - ROG STRIX-GTX1070-O8G-GAMING
Hard Drive 1 - Samsung 860 Evo 1tb
Hard Drive 2 - Samsung 850 Evo 250gb
Hard Drive 3 - Western Digital Blue 1tb
PSU - Corsair RMx 650w

Worth noting that there are a few hold over from my previous system - The GPU, PSU and hard drives 2 and 3, with the SSD being the original systems boot drive, and both got formatted (I think) when upgrading to the new system.

I have been through the usual Google Searches and with that updated drivers (and re-installed GPU drivers multiple times), been through windows memory test multiple times, and a few other bits that have escaped my mind. The only thing I have yet to do is reinstall Windows entirely and clear everything. Something I am loathe to do as Hard Drive 2 has a rather large Skyrim and Fallout install that took forever to get going.

Any help at all would be greatly appreciated! And thank you in advance.

Hello again.

Sorry to have to bump this as I really could use some help.

Had another BSOD this morning, this time with: Page fault in non paged area, and with something saying that ntfs.sys was the problem.

EDIT: Spent some time double and triple checking that I had all Drivers installed correctly, as aside from reinstalling Windows it's all that I can think of on my end. After which I reset the PC out of curiosity. Didn't get a blue screen (not unusual) but did pay attention the my debug LED's (never thought of that until browsing these forums. Two lit up when loading - the first flash was the top one which according to the mobo manual is "CPU not detected or failed" and the second flash was the bottom (out of four) which means "Boot device not detected or failed"

And today the system simply froze on the windows load screen. No beeps, no lights on the motherboard.

Going to try and see if disabling XMP and reinstalling Windows works.
