I have also gone through this same terrible situation When I had upgraded to Windows 10 from Windows 7.

 

I used Ccleaner, updated and reinstalled drivers, uninstalled and reinstalled all necessary programs, I uninstalled my antivirus hoping it will fix the issue.

 

My computer was running sluggishly, so I tried everything I knew in order to get it to work again.
