Basically. the computer just doesn't load, it freezes on the windows start up screen. I have a vista and the loading screen has the green bar at the bottom which indicates the start up and this continues to move but it doesn't load. I left it over night and woke up with the same screen. I have attempted to start it via safe mode and as safe mode starts a load of script scrolls down and then it freezes, restarts and stops back at the windows start up screen again.
When i force shut down, the option appears to start windows normally or (i cant remember the name of the option) when i choose the other option a blue screen appears and shuts down.
Its been like this for a month! I can't access my dissertation and i've been using this as procastination so I really need some help!
