Windows 10: BSOD errors after upgrading CPU and RAM?

So I upgraded my CPU and RAM last month, and after a week or so I started getting random bluescreens. It started with one random bsod when shutting down my pc though it happened too quick for me to note the error codes, on Feb 20th, then my pc was fine for a while. About 1 week later, my pc would randomly shut down and give the 'paged fault in nonpaged area' bsod - once while idly on desktop, and once while playing Apex Legends both on March 1st, and once more on the 2nd. I googled and ran WMDT which flagged a hardware error, so I replaced all my ram 4x8gb, which seemed to fix the WMDT e

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?

 

Video card or RAM need upgrading?

Memtest: no errors after 10 hrs.
I'm going to perform the Primetest, later on. Get back to you on that.
I'm going to take it step by step, guys. I need to find the problem with this current computer. I might have to upgrade some components, so that it is still runnable. As for the new one, yes....i will build on it later. I need to find something decent 'gaming experience', all suggestions appreciated. THanks.
