After last request “unraid kepping rebooting”

There turns out to be no solution

so i just buy another server to replace the last one 

At begianing it went queit well in two days ，and suddenly it died 

 

I dont know how to deal with it ，and I started to think is this may be my os problem？ my unraid flash drive is wrong？

or is there any way that I can pull my data pool setting out only without backup the whole flash？

 

Annnnnyone HELP！

Could be many things.  Power supply, mother board, etc. etc.  Can you troubleshoot?

How can I do this thanks

And one more tips ,the server which went died ,when it deal with windows sever os , it runs very well . So there might not be the hardware issue?

And then it comes to be the OS issue again

Make another USB boot disk with Unraid and try it.  If it boots fine then is your USB original disk.  Start with that
