Semi new rig boot loops after POST

[Boopig]

Hey guys. I'm typing this on my phone so please forgive any mistakes in my text.

Prime z370a
EVGA GTX 1080 superclocked
I7 8700k
16GB DDR4 3000mhz
EVGA 850w gold standard PSU

1x Kingston SSD
1x baracuda 2TB HDD
1x baracuda 3TB HDD
2x 140mm fans for my noctua cup cooler
9x 120mm fans for cooling

I built my new PC, reusing a few parts from my old rig. Those being the GPU, PSU, SSD and 2TB HDD. Keep in mind my reused parts are barely a year old.

After the PC was built it was fine. After 2 days one of the RAM sticks failed to register. I had a few bluescreens caused by memory issues and after I replaced the RAM the PC worked perfectly for several days before bluescreening out if nowhere.

Sadly, that was the last time I've been able to use my PC. Since then it posts then BSODs when trying to boot Windows. Whether it's installation media from my USB drive, a recovery environment from a USB drive or my OS installed on my SSD.

I've replaced the motherboard, tested the computer with each individual stick of RAM (I tried the two previous sticks before I sent them back) I've tried the PC without the fans, drives and GPU.

It only really leaves the PSU and CPU. I'm more leaning towards the CPU. But I feel if the CPU was faulty the PC wouldn't even post.

And if it was the PSU the results would be a little more inconsistent. But I'm really stumped at this point.

Any ideas guys?

Are you saying you replaced the motherboard and RAM and it still won't boot into windows?

What version of windows? A new fresh install or the install carried over from the SSD?

Is the BIOS updated and nothing overclocked (CPU and memory)? Including XMP mode for memory.

If its a fresh install of Windows 10 and the BIOS is updated and nothing is overclocked and assuming the cpu/gpu/psu are okay I would try reinstalling windows to a different drive. Any drive that is 100% blank and the only drive connected to the motherboard. Make sure the memory that you have is officially supported by your motherboard (a list should be on the manufactures website for that board) and don't enable XMP mode till everything is stable. Then see what happens.

I wiped my SSD in the BIOS to rule out any form of software or OS issue causing the boot looping. This is a hardware issue to be sure.

I've used multiple boot media's of recent and up to date Windows 10.

Nothing is overclocked, everything is running at it's factory settings and I've not touched anything in the BIOS.

I feel the only suspects are the PSU and CPU. Those are the only parts that haven't really been inspected fully. Would a PSU rail failing happen out of the blue? And cause boot looping so consistent?

And yes, I replaced both the motherboard and RAM.
