If your computer or mobile device is no longer under warranty, you can take it to a computer repair store. The repair guy will diagnose and solve the problem.
If you use Windows 8(.1) or 10, you can perform a PC reset, if you experience issues with your computer that you couldn’t resolve.
The PC reset feature (which is an equivalent of reset to factory defaults option on mobile devices) will quickly set Windows back to its factory-default state and delete everything (your personal data and applications you installed), fixing any system corruption problems and removing any buggy drivers or malware that’s causing problems. You will have to reinstall your installed applications afterwards.
To reset your computer (If your computer is booting properly):
Settings -> General option -> Advanced Startup -> choose Reset
Settings -> Update and Security -> Recovery -> Reset your PC.
Note: If your computer is not booting properly, you can reset it from the Advanced boot options menu.
