Dear @IT_WinSec:
Thank you for your reply!

Not a hardware problem: That's the thing. The issues still point to some kind of core CPU, RAM, or motherboard problem. However, I am out of ideas about what to test. How to test. If you have any ideas, shoot!
>> I don't think we/you have a clear clue yet what it is exactly.
The hardware diagnostics performed clearly shows no hardware issue. Looks like either Windows bug, or a driver incompatibility.
Have you disabled the automatic reboot yet ?
Is the BSOD code always the same (same error) ? You mentioned one it pointed to the audio, what was the other times ?
>> Did you check the Microsoft articles posted above and did you try Driver Verifier ?
What Windows 10 verison? Windows 10 Pro. Came with the machine.
>> Do you use the latest Windows 10 build 1809 or some previous ? You can check this in Control Panel -> System
Asking this because with Pro version, you are able to delay the installation of feature upgrade builds.
Reinstalled? I cleaned most of the HP bloatware from the machine because they added some delay to the boot. And there was a sound related software installed that I had to remove as well, as it caused one BSOD as well.
>> The fact that it does not clearly shows the same driver/sofware everytime when checking the dumps, mean this will be either Windows issue with memory management, or some hardware problem (most likely software), though
Power options: I did try these all, sadly. Hoped it was only a sleep / wake bug. But this didn't change anything. Even if the machine was left alone - it could BSOD.
Do you notice any issues being caused after not using the PC for certain period? Sadly, no. It's absolutely random. Sometimes the machine runs fine for hours, days. Sometimes it BSODs twice a day. It's just unreliable.
Antivirus: Just Defender, the default. Didn't want to mess with that until we made sure the laptop indeed works just fine.
I know. My reply, does not exactly help out here. If you have any BIOS setting idea, or whatever that might help, shoot. Willing to try anything to solve this once and for all. It really, really feels like there is a bent CPU pin, or some motherboard error.. it feels like a very sophisticated error. Something real "deep" that just does not show up. Even tried to disable deeper CPU sleep states - without luck. And my issue is, if I try running tests, they all come out clean. Yet the errors point to some deep system problem.
Now, you know, contact support. Sure. But as it rarely comes up, it would take them continuous day-to-day use to reproduce. No service team has time for that. Or they would just send it back, saying it didn't happen in a short while. Wish HP could look at the dumps, analyze them. Thought about swapping out the RAM in the machine, but I think the single 8GB module is on the side of the motherboard, and I'd rather not void any warranty just yet.
