I purchased a used Hp all in one desktop the other day. We did a reset to clear everything from the previous owners. Now it keeps looping back to the setup screen (the page that starts with " hi there, let's get a few basic things out of the way" then you select your country, language, time, and all that). After selecting the correct country and all I click next. It gives this sort of explaination answering why my computer restarted. I can't connect it to WiFi because it doesn't give the option, so I connected a cable from the modem to the monitor, I click next and it proceeds, screen will go black, blue saying 'just a moment's then black again, display the HP logo, then back to the blue setup. Now my question... What do I need to do to fix this?
