Whenever I press the WinKey on my Keyboard, I get an error which says Kernel caused a page fault error. It shows me a 'Show Detail' button. But it is useless, because my computer hangs at once and I have to press the Power Button. Now I have been using the Mouse to open the Start Menu. What could be the problem. I even installed Windows, formated hard disk & installed again and also set the BIOS settings to default. Yet no solution.
