On Sunday, I replaced my 15 year-old refurbished HP with a Dell Inspiron 3891, and here we are on Tuesday, the brand-new-out-of-the-box Dell has been hooked up to ethernet, power, monitor, keyboard and mouse, since Sunday night.  All I have been able to accomplish thus far is the country, language, keyboard type, and name the computer.  I have the white light on  on the power button.  Next to the card reader another white light blinks intermittently.  Under the ethernet plug, there's a steady green light.  On the monitor, it's a dark gray background, and the white cursor, which moved if I move the mouse.  After the first 24 hours, I shut it off, waited 5 minutes, and turned it back on.  That's when I got the country, language, and keyboard type questions.  Then the monitor displayed a dark gray background, and the white cursor, which moved if I moved the mouse  After the second 24 hours, I shut it off, waited 5 minutes, and turned it back on.   I got the country, language, and keyboard type questions, plus a screen where I could name my computer.  Then the monitor displayed a dark gray background, and the white cursor, which moved if I moved the mouse.  This morning, 18 hours later, I shut it off, waited 5 minutes, and turned it back on.  I got a blue screen that said it had to restart.  When it restarted, I got the assistant which scanned the drives for errors.  Scan said there were no problems, and back we went to the monitor displaying a dark gray background, and the white cursor, which moves if I moved the mouse.  That was an hour and 16 minutes ago.  I am sending this to you on a 10-year-old laptop, operating off the same internet connection as the new ; laptop on WiFi, Dell on Ethernet.  What am I missing?
