Windows 10: Suddenly freezing and rebooting if wait long enough, no error, no BSOD

Memtest comes out fine. RMA'd cpu. Reseated a bunch of cables. It still keeps freezing. Apparently, after some time during the freeze, it will reboot. What could possibly be the true problem?Waiting long enough during a freeze, to my surprise, eventually generated memory dumps without saying. I found out through event viewer.Said dump: https://1drv.ms/u/s!AuW7qWkHTgyoiFjAbZUBUQ-b2B0N?e=MmcohQ

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?

 

Computer Hard Freezes Randomly - No Error logs or Memory dumps


I posted on Sevenforums a few days ago regarding this issue:

I was suggested to check for temps (all were normal) and perform a clean install of Windows 10 (I had upgraded from Windows 7). I had another hard freeze today similar to the ones I was having before. The issue is back and I'm unsure of what to do next. Is this no longer a software issue if reinstalling the OS was unsuccessful?

Thanks for your time!
