Have you tried booting into safe mode? Press the F8 function key every second or so while the laptop boots. Choose Safe Mode with Networking. Go to Control Panel and choose Recovery. Follow the prompts.

If this doesn't work, it may be better to choose the option in safe mode to fix or repair startup problems.

Thanks for this reply

But I already tried this way and it doesn't respond when entering the windows,so if there any option except those.

Hi Ahmed

Thank you for reaching out here. Adding to what Abach has advised I request you to run diagnostics on the system and check for functionality and update me with the results. If the system boots up download and run Ccleaner and update me with the functionality. Kindly check the link mentioned below for steps to run the diagnostics on you system.
