Intel NUC 7i3 BNK keeps crashing

I got a used intel NUC from ebay and it seemed to work fine as a jellyfin server with quicksync but I have noticed that it has hard locked a few times and I’m not sure what is going on. I have opened it and cleaned the dust from the heatsink and ran memtest for the ram and both seemed to be okay. I am going to repaste with some kryonaut but if that doesn’t fix it I’m not sure what will. I have fedora running on it and jellyfin in docker and it works fine at times but then will randomly hardlock. I don’t really know what logs I should be looking into to see why the system just hardlocked or shutdown?

Any and all suggestions and help will be greatly appreciated.
