[SOLVED] Pc randomly shut down, won't even boot now.

[testchicken15]

Hey, couple days ago my PC just shut down, without Bluescreen or anything and then wouldn't even boot properly.
At first he crashed during boot a couple times, mostly with Bluescreen though, giving me the following error messages:
Kmode exception mit handled
System thread exception not handled
System service failed. Dxgsys
Page fault in nonpaged area
Critical process died
Everytime one of those, but no particular order. Since i thought it was a software/driver issue, i tried to uninstall recently installed updates via repair options, but it crashed every time within seconds of me trying. At one point i gave up for the day. Next day he wouldn't even turn on at all. I tried to unplug everything, checked every component, every cable, but nothing worked. Only thing that was on was a red CPU control LED on my motherboard. Fast forward 2 days, i rebuild it from scratch and i could turn it on again. Booting still won't work, but no crashes anymore.
Things i've tried: Starting in safe mode. Didn't work. sfc /scannow. Couldn't complete due to "windows resource protection could not perform the requested operation" chkdsk. No corrupt files. Then i tried to reinstall windows, but the installation bluescreens with: pfn list corrupt or irql not less vor equal as error message.
I tried to look up about every error message, googled every problem i had individually, but got no real answers. Could be about anything. The PC is roughly 4 month old and i could make use of my warranties, but what am i supposed to send in?
My rig:
650 Watt Seasonic Focus PX ATX 2.4 80 PLUS Platinum (115V) (FOCUS-PX-650)
6GB XFX Radeon RX 5600 XT THICC III Ultra Aktiv PCIe 4.0 x16 (Retail)
AMD Ryzen 5 3600 6x 3.60GHz So.AM4 BOX
500GB Samsung 970 Evo M.2 2280 NVMe PCIe 3.0 x4 32Gb/s 3D-NAND TLC (MZ-V7E500BW)
Gigabyte B450 Aorus Elite AMD B450 So.AM4 Dual Channel DDR4 ATX Retail
16GB G.Skill Flare X für AMD schwarz DDR4-3200 DIMM CL16 Dual Kit
Thanks in advance!

The system won't boot even in Safe Mode?
If you can enter Windows in Safe Mode disable Fast Startup

You could have a corrupted Windows installation. Try creating a new installation Media.

Try with only one RAM module and see if it boots.

A Dxgkrnl.sys BSOD is usually related to the video card drivers or in few cases a faulty GPU.
The Kmode exception not handled could be related to the same driver.

Try installing Windows on a different disk. Make sure to have only one disk connected during Windows setup.
If you are still getting the same issue then run Memtest86 from a USB and test you RAM.

Okay, thank you for the quick response. I don't have access to a different disk at the moment, but will do as soon as i can.
If both of those options give no result, what would be your next guess, if i may ask?

If the PC is powering on fine, does not power off by itself when in the BIOS, RAM passes the test , and only encounter issues when Windows is installed or been installed...then the issue is the disk, the Windows installation media or the GPU.
