My pc doesn’t turn on after changing a couple components. The CPU and DRAM led, light up on the PSC when I turn it on.

The components I changed out was:
PSU, motherboard, cpu cooler and the case.

Things I have tried:
I have tried changing all the old components back. I have tried testing it with another set of ram sticks. I have tried turning it on with only the cpu connected. I have tried testing if all the wires are fully connected.

Extra info:
The motherboard comes with a CD that I haven't tried using. As far as I can see it doesn’t say anything about it in the manual.

I don’t know if this matters but the new cooler isn’t fully aligned with the cpu even though it matches the socket of my cpu; i guess the mounting plate isn’t correct for the motherboard?

Specs:
CPU: AMD Ryzen 7 3700X
RAM: VENGEANCE® LPX 64GB (2 x 32GB) DDR4 DRAM 3200MHz C16
GPU: MSI NVidia geforce 2070 super
Motherboard: ASrock B550 PG Riptide
Cooler: noctua nh-d15 chromax.black
Case: Pop XL silent
PSU: Inter-Tech Argus GPS-800 800W
OS: Arch linux and windows 10 dualboot where linux is my daily driver
 
Welcome to the forums, newcomer!

We're goign to need to know a before and after of the specs. One for before the upgrade/swap and one after the upgrade/swap.

PSU: Inter-Tech Argus GPS-800 800W

^ this looks like a trash unit.

Have you tried breadboarding your platform?

RAM: VENGEANCE® LPX 64GB (2 x 32GB) DDR4 DRAM 3200MHz C16
Link to the ram kit?

I don’t know if this matters but the new cooler isn’t fully aligned with the cpu even though it matches the socket of my cpu; i guess the mounting plate isn’t correct for the motherboard?
Please include images. Host said images on a site akin to Imgur and then pass on a link to said image here so we can see it.

Trash as in bad or doesn’t work at all?

Have you tried breadboarding your platform?
No but I will get around to doing it.

First image is the mounting plate from the back. Second image is the top of the cpu where you can see that the cooler doesn't cover it completely. The last image is the bottom of the cpu where you can see the cooler extending further down then the cpu.
