    Black screen and wallpaper

    Since migrating to Win 10 about 2 months ago I have generally been very happy with it and find it much better than Win 8/8.1 but I have experienced a number of niggles around the screen functions - loss of task bar; black screens; loss of wallpaper or screensavers. What prompted me to make this posting was a specific problem today. My system is an HP Spectre 2 for 1 laptop/tablet running the most recent update of Win10 (Build 10240) on an Intel i5-5200U CPU with 8 Meg of RAM; I have the unit attached to a Samsung monitor through an HDMI connection but the screen problems seem to be reproduced even if I disconnect and use the laptop screen.

    Today I opened up the system and noticed that the taskbar at the bottom of the screen was missing. I should say that the last reboot of the laptop was probably 2-3 days ago as I think that these problems only seem to occur when the system has been running for quite a while. I tried clicking where the taskbar should have been but this had no effect in terms of launching/opening applications or files. I then minimised each of the open windows in turn until I ended up with a completely black screen but with the cursor visible and responsive.

    I tried the Windows key but nothing happens and none of the minimised files were visible. I could return to any opened files using Alt+Tab but nothing made the Taskbar return nor make the Windows key work - I also tried the Windows key in combination with Shift, Ctrl and Alt.
    Eventually I gave up and used Ctrl+Alt+Del to log-off and when I logged back on - i.e. did not reboot the system - everything was fine. Anyone know what is going on and how to stop this happening?

    The other problem I have had is that the desktop seems to regularly (~once a week) fail to find the wallpaper and /or screensaver files. When I open up Personalisation in the Settings menu and check the location of the image files it is looking in the correct folder, however when I click on Browse it tells me that the folder does not contain the files I am searching for. If I open File Manager and navigate to the same folder I can see that the files are in fact there. It appears as if at some times the utility is looking for a specific type of file and not identifying the JPEG and TIFF files in the folder as being suitable for wallpaper. If I redirect to a different folder and then point it back to the Wallpaper folder everything is fine again - at least for a week or so. I have not been able to link this behaviour to a specific set of circumstances. Anyone else had this problem?

    Run the System File Checker. Open a Command Prompt in admin mode and type:- sfc /scannow

    As the OS is OK, check for anything running in the background and run an AV scan with Malwarebytes Free.

    You might consider doing a repair with an in-place upgrade.

    Try rolling back to a Restore Point, well worth a shot.
