help figure which components are failing?

Hello,
i've been troubleshooting all day..

here's the situation,
most of my pc is working normally, except now the system starts to not detect my secondary SSD.
Then suddenly it detects and works without problems, only to fail again.
Now my pc only boots with 1 SSD connected, the other stops it from booting entirely.
my pc has also been having random shutdowns, and when powering on it immediately shuts down looping forever. At one point I then remove a ram stick and suddenly it boots without problems.
So i'm thinking maybe the PSU is malfunctioning.

So, today I got a new PSU (seasonic focus 850FX gold)
Same problems but even worse. Now with the new PSU both SSD's cause the pc to immediately shutdown after pressing the power button. I tried both SSd's by themselves and 2 different power cables for them. I swapped back to the old PSU and the 1 SSD boots ok, but only in a specific sata 3 slot. Sometimes the other ssd detects as well after lots of rebooting.

Could this be the motherboard or a mix of damaged components?

I would suggest making your system as simple as possible...even to the degree of loading a USB with Win 10 install or really anything that would boot to splash off that USB. Remove all peripherals, video card, etc. One stick of RAM. Try to boot it up into BIOS first, see what's there. Boot to the USB, see if it will even get to the part where it asks if you want to install. Assuming it would do that much, I would put your OS drive back and see if it will boot. If it does, start reinstalling parts until something causes issue. (which it sounds like you have)

As punkncat described, make your system as minimal as possible. Sounds like you have either a MB issue or multiple SSD issues. I seriously doubt it's you MB, how old are the SSD's? It very well could be something corrupt in the BIOS. I would check to see if your up to date on that and if not update to see if that helps.
