I was tearing my hair out this month. After my tech guy cleaned all the spyware off my Windows 8 for some reason my PC would go to sleep and slumber off into a deep hibernation and I could not awake it. Seriously, it made me scream because the only thing I could do was to hold my off/on button until it shutdown and then I turned it on again. This of course, closed all of my programs and browser pages. Aaaaaargh!
