Is it Windows 10? My wifes crashed and now goes into hibernation and could not come out of that state. We tried to reboot and new startup and it gives an error saying there is a damaged disk. We took it in and the tech guy said they are having a lot of that with Windows 10 update that was the last thing loaded. It apparently finds one fault in the disk, and instead of just using a different part or moving on, it stops and goes into stall mode. He said in previous versions and patches, the error would be ignored and life would go on. Our option is to get a new disk, new OS, and start from scratch. At least the tech guy saved off our files.
