Why does my PC reset its self everytime I launch my pc

[jakeger]

I logged onto my pc today and noticed that my background is missing as well as a lot of icons from my desk top. Every time I reboot my computer it does the exact same thing so all the files I had on my desktop go missing again, I also occasionally receive errors whilst trying to boot my PC

I don't remember the exact error I got but when I relaunched my pc I got a message saying that I have been logged in with a temporary profile
