Black screen with cursor after manufacturer logo (Windows 10).

[gustavo1]

I have a Lenovo Z40-70 (I3-4005U, Nvidia 820M 2GB, 8GB) with Windows 10, and for a few days i've been getting this issue, where after the manufacturer logo i get a black screen where i can move the cursor around.
I have to do a hard shutdown to get out, and sometimes i get to the windows recovery screen, but i system repair does nothing, neither does startup repair. I also can't get into safe mode, or any variations of it, so i can't try stuff like uninstalling my graphics driver... Also tried trying to log in blindly but was unable to.

I am booting with only the power cable plugged in.

Has anyone had this issue and solved it without having to lose data? I really would be bummed if i lost everything, because i have some valuable stuff in there.

EDIT: Now im on the black screen, but the cursor looks like its loading something (its in the blue circle shape), idk what its doing but thats that haha.

Try these...


Option 1 ...

1. First, while the computer is off, connect an external monitor.
2. Next turn on the computer and allow it to fully load.
3. Once loaded, press the "Windows Key" + "P" to open the "Easy Display Switcher".
4. In here select "Computer only".
5. Now shut down the computer and disconnect the external monitor.
5. Disconnect the external monitor
6. And finally restart the computer.


Option 2 ...

Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.

1. Press "Shift" repeatedly until the "sticky keys" window shows up.

2. Now click the the link there that will lead to the "Ease of Access Center".

3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.

4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.

5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).

6. Now click and open "System Restore".

7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.

8. The computer will now do the work it needs to and then reboot.


If that doesn't work, you can try the following...

You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.


If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)

Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....

SFC /SCANNOW

It will do a file check.
