"Critical Process Died"

Hi my Dell 8930 Pc took a dive an im left with this "Critical Process Died" BSOD.

I cant carry out a system restore point it fails. system restore error 0x80070002

cant acess safe mode it fails im taken back to a "Critical Process Died" BSOD.

DSIM runs gos thoughte process but dose not do anything same with SFC

Iv tried to re-write the boot sector etc still BSOD

been in the diskpart etc solutions also failed

• Run SFC and DISM: Still in Command Prompt, run the following to repair corrupted system files:
  sfc /scannow
dism /online /cleanup-image /restorehealth
• Fix Boot Records: If the system won't boot, use these commands in Command Prompt:
  bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

none of this worked

I can use a Hiren's BootCD (Windows Data Recovery) and get into a command prompt on desktop and run stuff from there but nothing seems to work. for every fix it just produces more errors that lead to you guessed it even more errors, i end up going down a rabbit hole of looking for fixes to fix fixes.

Surely someones had this issue and fixed it everntually. Iv spent many hours wasting my time watching youtube and going though guide after guide. is there anyone out there who can help?
