Windows 10: My PC recently had a BSOD when I wasn't present and I want to know why

I was downstairs at the time and when I came back up I saw that it had just restarted, and when I went to reliability history it said it was BSOD. I will attach my minidump files if anyone could tell me why? I've had maybe 2 before but that was when I was using a very old GPU that wasn't reliable and had maybe 5 years on it.https://1drv.ms/u/s!Ap1bokVyXWfCgQErU28s84WaJB8P?e=axzJt6Please let me know if it doesn't allow you to access the files.

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

For over a week my PC wasn`t responding at all. Blue screen of death and not able to boot. Tried everything to no avail.

For over a week my PC wasn`t responding at all. Blue screen of death and not able to boot. Tried everything to no avail. It made me believe that the problem was with my device. Decided to buy a new PC and at first use, Windows started playing up again.
Is Microsoft not responsible for this ? I should get my money back. IT IS A WINDOWS PROBLEM after all
