Why is my PC randomly displaying a stop code after my Windows 10 PC shut down? [closed]

I am running Windows 10 and my desktop randomly displayed a stop code after my PC shut down I wasn’t able to boot, only get into BIOS.

Not sure what caused it as I was multitasking, filling out a online form, running a Bitdefender full scan in the background

I am able to boot into safe mode but really need some expert troubleshooting steps on next steps.

  • While in safe mode are there any diagnostic checks I can run?
  • How do I diagnose the cause?
  • How do I prevent from happening again?
