Hello folks
I just bought some new parts for a (partially) new build. However, I have some difficulties with stability.
To start with the hardware is:
MB: MSI B550-A pro (newest bios)
CPU: Ryzen 5 5600x (Stock cooler)
Ram: 2x 8GB DDR4 3200mhz cl 16 (Compatible according to MB manufacturer and RAM manufacturer)
GPU: GTX1070 (And a working GTX680 for testing purposes)
First, the pc wouldn't POST at all. The fans were spinning and the lights came on, both on the MB, GPU, and CPU.
However, I got no output, no POST. The CPU debug light was solid white.
I figured that I would pull everything out of the case, reset CMOS, plugin a brand new CMOS battery and reseat everything. I also build it on top of a box instead of in the case.
Lo and behold, the pc could suddenly POST and do it consistently.
I figured that I would try to build it in the case again, and it still booted.
So now I think that I would be able to use it, at last.
But I log in to windows, the computer now keeps "restarting", or well, more like cutting the power and turning it on again (crashing without error message).
So I can use windows for like 10 seconds - then black screen and it boots again.
I noticed by pure coincidence that the debug light for DRAM is flashing for like a millisecond every time the computer "reboots", or cuts power.
I hope that perhaps someone here can help me figure out what is wrong.
Some of the things I have tried:
There is one caveat with the whole crashing stuff and that is that it is not doing it when I'm in the BIOS. And it seems to crash faster in windows if I try to use the pc. (usually, I only get to click on an icon before a crash)
I tried to come up with some possibilities for the crashes:

Some of the things I have tried:
- Booting with the minimum required hardware (1 ram stick etc.)
- Booting with one ram stick at a time, in all the slots
- Booting with confirmed working ram
- I have reseated the CPU and CPU cooler
- No bend pins on the CPU
- Cpu cooler is not overly tight
- Switched out GPU
- Reset CMOS
- Changed CMOS battery
- Made sure that the RAM is running standard speed
- Made sure that the standoffs are in the right position in the case
- CPU temps in bios are hovering around 35 degrees Celcius. (95 degrees Fahrenheit)

I tried to come up with some possibilities for the crashes:
- Shorting (I really can't see anything it should be shorting on - and wouldn't it do it in bios also if that's the case?)
- Faulty CPU
- Faulty motherboard
- Faulty PSU
