Windows 10: Frequent IRQL_LESS_OR_NOT_EQUAL BSODs

I am at my wits' end, and I need someone with more experience to please look at my info/dumps and hopefully at least nudge me in a direction to start looking at causes. Many and much thanks in advance.

I have developed consistent but not replicable BSOD crashes, mostly (but not always) with an IRQL_LESS_OR_NOT_EQUAL error in ntoskrnl.exe and ntkrnlmp.exe. (I don't know how much info you want on already taken steps, so I'll summarize what I have done and can provide more detail if asked.)

Developed, because my system was unchanged and this problem has become progressively worse, even as I have gotten more aggressive with troubleshooting.

Not replicable, because the crashes have occurred while I was: playing a game, browsing the web, watching video content through a media player, opening a file explorer window, while just sitting at the desktop while the system was doing nothing, etc. Longest time between crashes was something like four or five days, shortest about 30 minutes. After reboot, I can go right back to doing what I was doing and have no issues for some unknown period of time before crashing again while doing something else.

"Mostly" because I have gotten other stop codes, but not really since reinstalling Windows (which I did about a month ago).

Windows version: 20H2 (Build 19042.662)

Here is the archive created by the V2 log collector.

All drives pass the SeaTools "Long Generic" tests (no screenshots, sorry -- you'll have to take my word).

Driver verifier is running, but has not generated any useful info that I can determine.

I have run this forum's Tuneup.bat, and will paste the output below in a separate post.

Other steps taken:

• Updated all device and system drivers to most current versions
• Flashed all BIOS and firmware to newest versions
• Rolled back both the system and device drivers to various historic restore points
• Run memory checks (all passed)
• Replaced memory modules with new
• Monitors: removed/swapped, changed ports, changed cabling
• Uninstalled PCI audio device (my only expansion card apart from my GPU)
• Disassembled AMD graphics card and re-applied thermal compound (there was some notion on forum posts that the factory-applied thermal compound for my card might be prone to being insufficient/of poor quality and drying/cracking over time)
• Replaced AMD graphics card with a new NVIDIA graphics card
• Clean install of Windows 10 Pro N on a NEW SSD
• Targeted disabling/uninstalling of various devices via device manager

Next steps? And again, thank you in advance for your assistance.

BSOD error : IRQL_LESS_OR_NOT_EQUAL

I have been getting the same BSOD with the error: IRQL_LESS_OR_NOT_EQUAL. I have done and a clean install of windows and the problem is still occurring. If you have any idea of how to fix the error please let me know.

BSOD: driver irql_less_or_not_equal

I've been getting the occasional BSOD for a while now and finally fed up enough to do something about it. It varies what the BSOD says the cause is but the one I can remember is driver irql_less_or_not_equal. So I went and did the driver verifier and got
some minidumps. Couldn't even boot into windows with driver verifier on. Crashes seem to happen most often when I'm playing Overwatch (and no other games) and while watching videos on Youtube (Firefox)
