I have my new computer build but now I need to reformat the hard drive. I have the windows disk in but when it tells me to press any button it doesn't respond to my keyboard and goes into the start windows normally countdown screen. It wont respond to my keyboard on this either and when the time runs out it goes into a blue screen that says my computer has been shut off to prevent serious errors. When I turn it back on the same things happen over and over. Is this because the hard drive needs to be formated... If it does I would really like some help on how to reformat.
