Random BSoD crashes on TG01-0429 Gaming PC

[rosscosailor]

I purchased this PC in December 2020. About a month ago I started getting some ramdom BSoD mostly System Service Exception code.

Updated Nvidia GTX 1660S drivers, which also asked me to implement update to BIOS and presented me with a yes/no option. So I said yes, and the update went ahead.  Much to my dismay, the BIOS installed on my PC was F.30  for SSID 8767 !!!   Now my motherboard is an Erica with SSID 8643 so I would think the download of the SSID 8667-compatible BIOS was an incorrect attempted fix.

Since then the PC randomly crashed with BSoD with a number of messages including Stop-Kernal Mode_Heap_corruption, DPC_watchdog_violation, Kmode_exception_not_handled, etc.

Today I installed the new F.31 BIOS update (for SSID 8643) which loaded correctly, but I am still getting BSoD.

My installed OS version from "System Information Screen" is 2009 (10.0.19042).  Winver shows "Version 20H2 (OS Build 19042.964)".

I have run all the hardware diagnostics - Passed.

My question to the forum is has this "BIOS " activity corrupted the OS to the point where I should reinstall windows?

HP Support Assistant says my  PC is up to date with all software and drivers.

If reinstall is the way to go, what version should I use and what is the best approach to do so??

I am a real novice at this and this is my first post to the forum.  Can someone help point me in the right direction.   I am spinning my wheels.  Thank you.

Do you have a "spare" disk-drive? 

If so, disconnect from the Internet, by removing the Ethernet cable.

If you have downloaded a device-driver installer for your video-card, copy it to a USB memory-stick.

Shutdown.

Disconnect the power-cord.

Disconnect your current disk-drive.

Connect the spare disk-drive.

Reinstall Windows.

Install the device-driver from the USB memory-stick.

Try to use the computer, even though you don't have the latest Windows Updates, and no Internet connection.

If it still BSODs, then your have learned that the original disk-drive, and your Windows installation, probably is fine.
