Bootloop beyond repair after playing a video with MPC-HC (with K-Lite installed a few days ago).

Hello there. It's the second time within the first year of my new PC that I am running into this ghastly, unrepairable Windows 10 BSOD / bootloop which appears to be somehow connected with MPC-HC and K-Lite Codec pack.
I am saying this, because both times, it all started after playing a seemingly random video with MPC-HC. The circumstances were pretty similar in both cases, but I think I should mention as much details as possible.
The reason I am posting here is because at least with Bootloop #2 (but quite possibly before the first one occurs too), I installed the K-Lite Codec Pack a couple of days ago (latest version, from the legit, official Codecguide site of course, that also linked me tot his forum).
Researching online, I've figured many people advising against using K-Lite (and installing only the codec you want instead), because it can cause various problems, including bootloops so I am now pretty skeptical about it and I've figured it'd be a good idea to just ask you about those claims and whether you have any ideas about what's happening, why it does, how could I possibly escape the bootloop when that happened and of course, most importantly, what should I do to make perfectly sure this isn't happening ever again.

Bootloop 1, a few months ago: Upon playing a .ts recording, stored on a Sandisk micro sd card, connected via a micro sd external usb adapter. I record TV programs using a DVBT-T2 receiver in .ts format, then edit them on PC or simply view them with video players (includ. MPC-HC), usually with no problems, meaning it was not the first time I did that.
Upon launching it with MPC-HC, the message "DX9AllocatorPresenter failed D3DERR_NOTAVAILABLE" appeared and I remember the video being flipped upside down (I can't recall if sound was playing or not).
Interestingly, the system didn't instantly BSODed so I didn't even realize something was (seriously) wrong.
On the very next boot though, a little later, Windows failed to boot, "CRITICAL DEVICE FAILED" message (unfortunately there was no code) appeared, then I am stuck in a dreaded bootloop limbo where no safe mode, disabling driver signature enforcement or other advanced startup setting or typical cmd line wizardry (fixboot/dism etc.) was able to do anything about it.
Fortunately, "System Restore" came to rescue back then, and I was able to recover my system to a previously working state.

I've started being a bit hesitant to keep using MPC-HC, so because of this, I've also started using GOM Player as my main player but still kept using MPC-HC now and then (as a secondary player), mainly while connecting my PC to my TV via HDMI to watch x265/10 bit encoded movies (it works really well with an android remote control app, which is convenient) and because well... it's the player I've learnt to love through the years.

Bootloop 2, a week ago. This time I had demuxed a .mkv, downloaded off youtube (stored locally on my hard drive) into elementary H.264 and .wav streams using Videoredo and the idea was remux the elementary H.264 with another .wav with Mkvtoolnix or Videoredo etc. But first, I wanted to load the video in a player then load the .wav file stream separately, so I test audio/video sync, adjust the audio accordingly, then note down how many ms I need to add or subtract, so I set the right sync on Mkvtoolnix later. I've opened the H.264 stream with Gom Player and I wasn't able to find a "load external audio stream option" (as I wasn't able to find it one on MPC-HC, but this is not our problem). It didn't show any error messages though. So I thought I'd give MPC-HC a go. Upon opening it, the "DX9AllocatorPresenter failed D3DERR_NOTAVAILABLE" showed up once more (this time without the video being upside down).
I said to myself: "Uh oh", because I knew what that meant... So I've rebooted my system and... sure enough... I was facing the exact same bootloop... Only this time, not even "System Restore" or even "Reset this PC" was able to save me (they both failed) and I was left with no choice but to reinstall Windows...

Now, I don't believe in recurring coincidences and I am sure you understand how why I suspect that MPC-HC and K-Lite might (at least partially) be responsible for my bootloops. But I am not here to point fingers or accuse by any means, so please don't see it like that. I am here hoping you can help me understand what's happening and most importantly prevent it from happening again.
I could be way off, but it looks like those two times MPC-HC was asked to play two files that for some reason didn't like (possibly conflicting K-lite codecs?) and for whatever reason corrupted something on my system (most likely the video card driver) which Windows didn't like at all ,to the point they could not possibly recover...  I really hope you can help me get to the bottom of this.
Thanks a lot for your time and consideration.

Not fault of player or codecs. It is a hardware or driver issue.

Your topic on MPC-HC issue tracker has good tips to try.

Regardless of the opinion one might have about using codec packs or not, you were right. I found the root cause of the issue and it had nothing to do with MPC-HC or K-Lite indeed. If I you'd like me to delete or edit my original message to highlight this fact, let me know.
