Windows 10: PC Crash/Restart - No BSOD

Hello,I got a relatively decent PC. Don't have issues that often, but with certain games -recently- my PC crashes and restarts without going into BSOD. I kept an eye on thermals and they seem fine. I also checked on my drivers and made sure they were up to date. I will attach the minidump logs, any help is truly appreciated!Thank you in advance.Please find the logs here.p.s. I have been told previously that my GPU driver was the causing it, I have re-installed it using DDU which helped a bit but the issue is still there

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?

 

Random Restarts, No BSOD

He mentioned that he had done that above. Also I provided a BSOD details app. There were no BSODs to report.

 

Random Restarts, No BSOD

Reboot and hit F8 to get into the Windows Diagnostic Settings before Windows boots. Turn off "Automatic Restart on System Failure." This way we can completely rule out BSODs. Sometimes a PC will BSOD but the PC will restart so quickly that the BSOD is not even rendered.
