ok today I went on the computer and it was all normal then I shut it off a few hours later I go back on and it starts up but completly nothing shows up on my desktop except for the wallpaper. I restart a few times and still, nothing shows up. So I turn is back off and a few hours later I try again but this time when I start it up it doesn't even want to boot all the way. What happens is that the Vaio logo shows and then the sign that says pentium four procesor comes up to but after that it just restarts itself over again. I tired to put it on in safe mode but it doesn't work I also tried putting in the Windows XP but it doesn't boot with that either. I kept trying but the same thing just happes over and over again. Would you happen to know whats wrong with it?
