Have you tried going back to before the mishap and restoring your computer to a previous time earlier than the one you say you used when it didnot come back after it tried to recover? I am thinking . . . Did Windows do an update right before all the problems started to occur? I just had to do a Recovery due to some glitch that showed up after a Windows Critical Update. For some reason I could not boot from my hard drive no matter what I did to the boot priorities in the Motherboard BIOS after the update. I now have Windows update set to download but let me decide whether or not to install updates so I can check on line to see if there have been problems after other people have installed a particular update.
Try this if you can only get black screen:
Start your computer in safe mode Safe mode starts Windows with a limited set of files and
drivers. Startup programs don't run in safe mode, and only the basic drivers needed to start Windows are installed. For more information, see
What is safe mode?
Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent Windows from starting correctly. If a problem doesn't reappear when you start in safe mode, you can eliminate the
default settings and basic device drivers as possible causes. If a recently installed program, device, or driver prevents Windows from running correctly, you can start your computer in safe mode and then remove the program that's causing the problem.
