RE: Black screen background and no access to start menu
Thanks for reply. My Dell laptop is Inspiron 17 5000 series - quite new.
I managed to resolve the problem by shutting down and holding power button for 15 secs - normal shut down and restart didn't initially sort the problem.
I had recently upgraded to Windows 10 - and dont recall doing anything unusual or changing any settngs that might account for this problem. I see from the Dell help page that there may be a problem with Win 10 on some laptops? I might have to download some update of firmware?? This is surprising, because I thought they did a diagnostics test for compatability before I downloaded Win 10.
It hasn't happened again TG.
