Windows Files Corrupted, Possible Hardware Issues can't Boot Windows

Hi,

I purchased A PC a little over a year ago and everything has been fine up until five days ago. I could boot to windows, but within 15 minutes or so of normal function it would freeze with whatever sound was being output looping into a loud buzzing sound.

I started monitoring my voltages and heat during these 15 minute stints and nothing was out of the ordinary.

Friday windows failed to boot so I went into cmd and ran sfc /scannow and it reported corrupted windows files.

I have windows on its own SSD separate from my HDD that holds my other programs etc., So I reinstalled windows from the windows boot menu.

The reinstall went through just fine, but the freezing continued. I booted in safe mode and ran "DISM.exe /Online /Cleanup-image /Restorehealth" and it got to about 80% before telling me it had failed.

Went on a trip for a couple days and now my PC won't boot to windows, it freezes at the loading screen for my Mobo (MSI, little circles spinning) I can get into BIOS and change boot orders and all, but can't get Windows to do anything but blue screen, even on a Bootable windows install USB. So I individually went through the boot order and disabled each item to check them each and it still froze every time, at varying times.

I removed the SSD (but not the HDD) and it still froze.

I removed my GPU and it still froze.

I removed both the GPU and SSD and it froze.

Also I ran each stick of RAM in each port both together and individually, covering each permutation, to no avail.

Sometimes the BSOD for W10 fully appears, sometimes it freezes after a few displayed characters ("Your PC team into a pro" etc.) And each time I get different Stop codes. I've gotten IRQL NOT LESS OR EQUAL, an MCE (though this is without the SSD, mouse and keyboard attached,) and one or two others I can't remember.

Can I do something with the EFI Shell functionality?

What's the next step?

According to my buy order from the website, I have a 3 year service plan, and I am by no means a professional, more of a hobbyist, is there an easy fix or do I send it in?
