What PC hardware diagnostic stress-testing freeware can you recommend?

o I have a random hardware related BSOD whose cause is unknown to me

It could be the motherboard, a daughter card, the HDD mechanics, etc.

I first ran the Windows memory diagnostic freeware to no avail:

As per the kind suggestions of "n/a" and others, I ran memtest86 freeware
on that old BIOS desktop in an attempt to identify its hardware faults:

The old BIOS desktop booted a 32GB Memtest86 USB stick to ran overnight,
finding no errors on 16GB RAM (I stopped it after 5 hours & 6 iterations):

If it's not the RAM, it's something else hardware related (the HDD has been
re-imaged multiple times in its entirety and all extraneous boards and
peripherals have been disconnected).

What other hardware diagnostic stress-testing freeware can you further recommend?

Usenet is a wonderfully public way to identify freeware of interest.
