Windows 10: PC Crashes, bsod, dmp - kernel error

I am pretty savvy and have run many stress tests, reinstalls, drivers updates one by one and can't seem to find the issues that are causing random crashes. I get some random power shut downs eventually I'll corrupt windows after a couple weeks and have to start over. Very annoying but I'm not looking to rebuild this PC as it's pretty new. I have some dmp files from past crashes but no bluescreen data yet as I just installed windows and it hasn't gotten that bad yet. it willcan anyone help or where should I go for this type of help? Thanks

Power issue with the kernel, and the Kernel Security Check Failure BSODs

I have been getting 'Kernel Security Check Failure' BSODs sometimes when I start the vpn client or rarely when I start Kaspersky 17, but never ever when I play demanding games and never while browsing. And today in Windows Events I found the error is kernel power. Yes, I changed the PSU (to CORSAIR CS850M), but do the symptoms say so? Nvidia driver updated, temps are fine too.

Here's a screenshot of the dump files.

 

Several Kernel Errors within a day?


Lets get back to this troubleshooting step *Arrow Several Kernel Errors within a day? - Page 2 - Windows 10 Forums
The result was a working system in safe mode, though the GPU isn't used in safe mode.
Please perform a clean boot again, watch the temperatures at all times (if you didn't yet) and from there we'll see what needs to be done. Please do not enable anything in taskmanager & msconfig, I want you to boot without any startup items & services enabled.

What was the BSOD stop code? Based on the BSOD stop code I'll edit the suggestion in this post.

 

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?
