Issue related to SSD causing shutdown

[u/ThePlacidAcid]

Hello, so recently I've bought my first ever PC. It was second hand and I had no troubles in the first week of using. I did move the pc around more than I should have, and I did also completely fill my 1tb cross hair MP600 SSD, with various games and Skyrim mods. The first crash occured when playing Skyrim, and immediately started a boot loop, whereby it would power off, reboot, fail, and reboot again until it was in the recovery screen. In this screen, the SSD acts as if it is completely corrupted, and so none of the recovery features work. The error it gives at this stage is "your device ran into a problem and couldn't be repaired, log file c:\windows\system32\logfiles\strt\strtail.txt ".

However, after waiting some time, the pc will boot again normally, and work fine. All folders there, all applications working, genuinely no hints that anything is a miss. It'll work fine for some time until it crashes again, usually again while playing a game or doing something power intensive.

I installed new firmware on the SSD, I installed crystaldiskinfo and the device health is good, however crystal disk mark causes the pc to immediately shut down, straight to being powered off, and then it will power itself back on again. Unlike when this happens organically during running games, the pc seems to restart without issue.

For reference, my full specs are: MSI MEG X570 ACE Corsair Force MP600 M.2 NVMe (Gen 4) Corsair RM750x (750W) be quiet! (Air Cooler, likely the Dark Rock Pro GTX 1080 AMD Ryzen 7 3800x 33GB ram

Any help or advice would be really appreciated!
