Have a Dell Inspiron 3847 running Windows 10 Pro (64-bit) and when I boot from Power On,, the Dell logo is displayed for 3 to 4 minutes before Windows starts(i.e. when the blue window logo displays). After that, Windows starts correctly..
I'm tempted to say that it's a hardware problem – EXCEPT – it doesn't happen when I do a RESTART… only when the computer is powered on (i.e. after a SHUTDOWN – most often from the day before, but really anytime).
I tried turning off the Fast Startup but no joy!
Problem started when I was installing a new router (but computer was turned off before starting the install – and was turned back on before the hardware was actually connected).
Does anyone know what Windows does before displaying the blue windows logo?
As I said, Windows completes the boot successfully – in the same amount of time as previously – and subsequent executions are correct.
