Sir my laptop pops up screen sometimes and if press anything it shows a black screen with cursor . Mouse is completely working . What should I do to fix this ??
That is the sign on screen you are showing, that is what I assume what you meant by "pops up screen". The sign on screen will show after 10 mins of inactivity.
From the Start menu find Command prompt, right click and choose Run as Admin. Then type in "sfc /scannow" and let it fix any errors automatically.
Power on the machine, don't wait for Windows to load and hard power off. Do this 3 times and Windows will detect something is wrong and offer you the troubleshooter. Go into the menu and located Startup Repair.
Actually the issue is that the lock screen that appears before entering password is visible . But when I press anything the screen used to become black . I entered the password and all of a sudden my desktop opened . I immediately solved the issues by troubleshooting .You can see the pictures in my first text to understand .
