Hi, All of a sudden my aspire one with XP started showing blank screen. I haven't used a lot of hard drive so I don't know if its the hard drive thats not working or the screen because after pressing the power button, I hear the hard drive noise but that it and no light, even when I press caps button that light is not lit (the green light on front). The screen is blanks and nothing is showing. Can you please help me out with this problem? Thanks
