I've been having BSOD crashes for the last 3 weeks, they happen daily at this point. The error code is always the same: CRITICAL_PROCESS_DIED. Usually happens during the first cold boot of the day. Sometimes it happens during the boot process, other times about 15-30 seconds after I've logged in.

Right after a crash it restarts and freezes at the Alienware logo screen. After manually powering off and on again, the primary boot drive isn't detected and I get a No Boot media Found message.(Model SanDisk X400 M.2 2280 128GB) It doesn't show up in the BIOS either. I have to restart a few times and run the Alienware diagnostic a few times, before it detects the SSD again, at which point it runs smoothly, and im able to use the system throughout the day without any more crashes or issues. 

Initially, I tried reinstalling and updating drivers for hardware components. Then reinstalled windows using the reset option in the recovery settings. It did not solve the problem. 

After speaking to Dell tech support, I did a clean installation of windows from a USB drive. It didn't help.

The Alienware preboot assessment finds no errors when the SSD is being detected in the BIOS. Otherwise, I get a no Boot drive found message. Or, it happened twice that I got an Error code -2000-0151, an HDD-related error. 

Yesterday I tried the diagnostic tools on the Dell website using support assist. While running the full 40 min test the first time, it crashed during the 'Fixed transformation and Lighting Test'. On the second attempt, it passed all the tests except the battery, which does not give any backup for the last 2+ years, so it's not a new issue. 

Here is the latest detailed dump file:

And the dxdiag report:

I am no longer covered under warranty, and contacting Dell support here didn't help much apart from being told to reinstall windows again. They wouldn't even listen to a detailed description of the problem. 

I use this computer for work and it's crucial for me to get it fixed ASAP.
