Question SSD stopped working and replacement SSD stopped working

[CPUmagnus]

After a game-update (valorent) my computer booted into EFI shell, rebooted into BIOS and it could not see any drives connected to SATA ports. This is what I tried: (all without luck)

1. Tried another SATA-port, and another cable.
2. Connected another SSD, seemed like it read it but I shut the computer off because I was trying my original SSD on another computer. When I retried this SSD BIOS could not find it.
3. Tried another powercable from my PSU.

4.Tried the original SSD on another computer but it froze on the asus logo.
5.I bought a dock to connect the drives to my laptop but no-go.

Any suggestions? Could my PSU be frying my harddrives?
I now ordered a M2.SSD , should I be worried about connecting it to my motherboard?
Can a new PSU be the solution, or a motherboard?
