I upgraded my Lenovo Z570 to Windows 8.1 and have been encountering lots of problems. I'm unable to boot after restarting. So every time it enters sleep mode or restarts, I have to shut it down using the power button and then restart. I've unchecked the Fast start-up option too but there's no use. Also tried Automatic Repair but it doesn't work.
