Macbook Pro 2012 freezing issues

I have been facing issue wrt my macbook pro 2012 since last few months.

 

In the middle of session the cursor will stop responding or will become too slow to my actions. All other keys will also become non-responsive during that time period.

 

Sometimes I am able to resolve the issue by putting my device to sleep (if I am able to move my cursor to sleep option); else I have to reboot.

 

I am rebooting 3 - 4 times a week at the moment.

 

I work from home and dont recall a moment when device has fallen or mishandled (I am the only user)

 

Any help and recommendation will be appreciated.

Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.

  6. Install Combo Updater Download 10.12.6 Combo Update and install.
  7. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
