|Have you a link to that post you are referring to please? Otherwise let us have the background to your problems. It is possible that you have hard disk trouble but you could try this as has been known at odd times to fix computers that have become stuck:|
Turn off computer and disconnect from domestic power. If it is a laptop remove the main battery too. Finally hold the Power Off/On button down for at least 20 seconds to discharge the motherboard components. It's a bit hopeful but quick to try.
Make sure you have nothing in any of your drives (like a disc or a flash drive).
Always pop back and let us know the outcome - thanks
