Black screen no login after screen saver

Hi

Just been away from my computer and came back and tapped the keyboard to get a PIN login but all I got was a black screen with moving mouse cursor so had to do a hard reset. Running creators update 15063.332. Any ideas?

Thanks Ken, Graphics driver was updated by windows update last few days but thinking it was that I updated to latest Nvidia driver from Nvidia site as a precaution. Hibernation and sleep are off on this machine so when I leave the machine screen saver kicks in after 29 minutes and screen turns off after 30 minutes. Nothing in Event log or Reliability history apart from the machine not shut down correctly which would have been the hard reset. Although the graphics drivers have recently been updated by windows update the machine did freeze once before after I left it for 30 minutes with sound repeating and mouse frozen. That time I updated the sound drivers with latest from Realtek. Thanks for your thoughts.

Thanks for the thoughts have changed the screensaver from 3D Text to Blank and re-applied the hibernation setting. See if that has any effect. It seems to happen after the machine has been up for a number of days. So far twice today it has normally returned to lock screen and I was able to login normally.

Have spent about an hour updating drivers including Realtek Sound drivers from MS Catalog. So will run for a while and see if there are any repeats of the freeze or black screen.

Hi, ist time poster.

I'm having this startup, black screen with cursor nightmare too--hangs on Black screen at startup for an hour before it goes to the sign on screen. Been Googling and watching youtube "fix" vids like a maniac for 3 days now (a lot of Windows 10 hatred out there).

On one of the vids, the "tech guy" who did the vid wrote that if you can see ANYTHING (his emphasis) on your screen when it hangs, it's not a hard drive problem. Is this true?? I don't want to bring it into Best Buy (if I can't resolve this) and pay 150 bucks for a diagnostic just to be told my hard drive's fried and I need a new computer.

When my computer's running, it works fine. I've been leaving it on 24/7 and using Sleep Mode when I'm not using it.

Any help would be greatly appreciated.

Thanks.

Think I may have found the Culprit. Installed the latest Logitech Keyboard Driver and it was taking lots of CPU resources. So went back to the old version of the software V8.53 and as soon as I installed it I got a blue screen of death. So with V8.94 buggy taking too many CPU resources I googled older versions and have installed V8.84 as V8.89 gets stuck at the installation dialogue. So far so good.

After searching the Logitech Forums there is a solution for the high CPU use on the latest driver so re-installed V8.94 and we will see if this is the culprit or not.
