My computer is driving me crazy! Sometimes, when I turn it on, it boots up immediately. But other times, the hard disk diode just stays lit and does not start the Windows (XP). It takes several restart button actions to boot up. I reinstalled Windows and all the drivers but it just feels like it may be a mechanical problem and not the software? Please help!
