Windows 10: Laptop boots up but occasionally gets "Boot Device not found, Error 3F0"

Hi, This problem started a few months ago when my laptop was running Windows 10. I usually put my laptop to sleep to preserve ongoing work, and it started giving me the error "Boot Device not found". But it allows me to boot up normally after exiting the Windows Diagnostics screen.I have done most of the fixes I have seen online. The diagnostics test Memory and Quick + Extensive Hard Drive all returned positive. I have reset BIOS settings to default, edited the bootup options to boot on my SSD first, updated my BIOS, and even tried booting up on Legacy mode. I also tried opening up my laptop

:)

 

3f0 no OS found Error HP. Sometimes can boot into drive!

Experiencing occasional Error 3F0 boot error, Windows Event Viewer shows "Kernel-Power" error with various BugcheckCodes

Bugcheck Code: 292 or 340 or 239 or 0 or 122

Source has been listed as "Kernel-Power" for every Critical shutdown error with an event ID of 41, and a Task Category of 63.

Latest one is a Bugcheck Code of 292 at about 6PM Eastern US Time of May 19th (today at time of writing).

The issue I've been experiencing was a 3F0 error upon boot (occasionally, but far too many times for it to be acceptable considering the laptop is about 6 months old). I've already contacted HP about it, but they're running through their diagnostic thing, but I've also seen posts about this, and I just wanted to see if someone else could help figure out the issue here causing the 3F0 (no boot drive, I think) error.

Please let me know if anyone need info to potentially help figure out the cause, I'm kind of desperate at this point, and HP likely won't replace it as it's a custom spec-d laptop without having to run through their diagnostic routine.
