I am having this sever issue where my laptop will just randomly give BSOD.
First it was WHEA_UNCORRECTABLE_ERROR. At the time my machine had 2004 version of Windows 10 (Home) and BIOS version F.14. I tried everything including HP Cloud Recovery but every two/three days, I'll get this BSOD and this time reduces to two days and then suddenly system does not boot.
I Installed an old version of windows which will only update to version 1909 and wouldn't update any further nad updated the BIOS to F.15. System was working fine. Then I upgraded my system's BIOS to latest (F.20) from here https://support.hp.com/us-en/drivers/selfservice/omen-15-dh1000-laptop-pc-series/32827277/model/3282...
1 day later I am getting BSODs with CRITICAL_PROCESS_DIED. Again in one day same BSOD. This time I install a pro version of windows which (again) will not update beyond 1909 version. But BSOD still happens again today.
I think the updated BIOS is the culprit here.
I am unable to downgrade the BIOS to previous version. I have tried using USB recovery (Win+B key method) and HP Diagnostics - UEFI, BIOS roll back, both fail. Also tried downloading and installing the previous BIOS version, where the first option to downgrade is greyed out with warning that it is not gonna happen.
The Window+B key method does not show Bios prompt keeps showing black screen despite waiting 10 minutes.
I need help regarding the main issue.
- How to get rid of this BSOD?
- If downgrading the BIOS is the solution, How do I downgrade the BIOS (which currently fails)

i suggest you post your question to one of the other non-business related forums... this is a business forum where the expertise on these type of systems
I would say that sometimes BIOS have security fixes that will prevent rollbacks, but can't comment on your gaming laptop... i would, perhaps, backup your data, and do a Windows reset? i assume you have updated all drivers and s/w in your laptop

Yes all the drivers are updated.
I installed the windows AFTER the BIOS update, how does resetting can solve this issue?
Whatever the new BIOS update has inside, it is most causing BSODs. Before this update there was no such issue. Also, carefully looking into the Reliability Monitor, i see that after or before the BSOD crash, there is this critical error:
Summary: Stopped Working, Critical Event: Controls the DTS audio processing object
could this be the actual culprit ?
