Question 0xc000021a BSoD

[Namiklan]

So a couple of months ago I had gotten a Z390 -A Pro replacement mobo for my birthday. It's kinda blurry, the events leading up to my problem. But one day I went to start up my computer and started getting BSoD errors,(the few I can remember are, "IRQL_NOT_LESS_OR_EQUAL", "MEMORY_MANAGEMENT", "PAGE_FAULT_IN_NONPAGED_AREA", and "0xc000021a". It didn't start off that bad, only occurring randomly, but over some time it got constant. I ended up short-circuiting my mobo and completely screwed it. I sold that set of ram to a friend for a new pair of headphones because I got a new kit of ram thinking that was the problem. Now recently I just bought a new mobo and once I got everything installed, I WAS STILL GETTING THE SAME ISSUES, mainly "0xc000021a". I slapped Windows 10 media creation tool on my USB and when loading that up I was still getting the same error as trying to load the OS. I kept at it tho and I got into the media screen. I had been thinking about it for a while prior to all this error crap. I formatted all my drives and installed windows 10. But the install BSoD-ed and got ruined. I'm at a loss right now to what the hell could be the problem. I was still getting the error with-out an OS. I tried to install, CentOS and Windows 8.1, which I was able to install Windows 8.1 and boot into. I had a separate USB with BSoD Viewer and all my BSoDs were related to, "ntoskrnl.exe" which would explain the kernel crashes. But I haven't been able to but into since and it only goes as far as auto repair. MemTest86 get 10k errors with-in the 25% of pass 1 with both DIMMs and it stops the test. I tried them separately. Both getting a substantial amount of errors. I've also tried to start up with only the essentials in it, and still, it leads me to the same thing.

~thank you in advance for helping me!!!!

I wasn't being a dick about it, I was genuinely wondering.
But my problem is I can't boot into windows. the furthest I get is WindowsPE Recovery.

That's all you need, Prime95 doesn't need Windows to work, it's a bootable USB. So if you can make it on another PC, and test it, it can help identify if it really is the CPU at fault.

I'm 90% sure tho that it's being caused by a driver. But I don't know how to update them if I can't even boot to do it.

It can't be if you're encountering the issue during fresh installs.
If you're getting crashes even simply when trying to install an OS, the drivers haven't even loaded yet.

Also hardware failures typically result in a variety of bugchecks, drivers often tend to have a more streamlined results (I.e. Thread Exception repeatedly).

The basis of it would be, if you clean install Windows and the problem disappears, it was core OS corruption or driver. This is why we recommend removing all devices possible when reinstalling to prevent any potential conflict.

If the crashes still occur during installation or after the clean install, then it's firmware (BIOS) or hardware.

I found something interesting. I'm using the "ultimate boot cd". and I was looking around and CPUID is saying:
Warning: unknown intel cache entry: 0x63
Warning: unknown intel cache entry: 0x76
Warning: unknown intel cache entry: 0xFF
Warning: unknown intel cache entry: 0xB6
Warning: unknown intel cache entry: 0xC3

That could be signs of a faulty CPU as it could be faulty cache. First port of call for me would be to remove the CPU, and inspect the CPU and socket for damage or bent pins. This can also cause this issue.

Did you get this when running prime95 or memtest? Memtest also tests intel cache but usually can't differentiate the difference.

I loaded up a separate program in a bootable os, https://www.ultimatebootcd.com/download.html, called "x86test-0.10a" under CPU.
And as for prime95, after a minuter on test#2 it leaves me with a blank screen after a while

Now i found a few things about blank screen on test 2 meaning its possibly power...

Prime 95 has 4 tests

1. Small FFTs

The Small FFTs description in the dialog box says maximum FPU stress, data fits in L2 Cache and RAM not tested. This is what the Small FFTs configuration is. If you select this configuration, the Prime95 will select a FFT size that is suitable for your CPY L2 cache. Since this FFT is small and fits in your CPU cache, this will result in almost no or very few main memory accesses.

2. In-place large FFTs

This configuration, as the name suggests, uses large FFTs. Unlike Small FFTs, these large FFTs won’t fit in your CPU cache so it will result in a lot of main memory accesses when compared to the Small FFTs. However, it doesn’t access the main memory a lot in general mainly because it accesses the same portions of RAM over and over again.

3. Blend

The Blend mode mixes both the Small FFTs and the Large FFTs. This means that it will select both small as well as large FFT sizes. The small FFT sizes will test your CPU more (just like the small FFTs) and large FFT sizes won’t be enough for the CPU cache so they will use the memory as well. So, it is obvious that with Blend mode you will test both your CPU and your RAM as well.

4. Custom

So test 2 looks at the memory controller on CPU and ram usage
since you have new ram and motherboard, it could be the CPU was cause all along
