My MB page glitches sometimes

When I go to one page and then another, my page doesn't load properly and shows a "nothing found" message. I reload, nothing happens, I reload for the thousandth time and still nothing. When I go back to the Google page and then to the MB page, it works. Is the problem my computer or my internet? I know this isn't the right topic, but can someone explain what's happening with my MB page? this happens sometimes
