I decided to restart my laptop and this is where my problem started. Since the restart the laptop will not reboot. It gets as far as the options of start windows normally, at last known settings that worked, in safe mode. I have tried all these options and on doing so the system progresses to the window xp loading screen and this is where it stops. I have tried rebooting from the disk but the reboot does not even get that far as it is stuck on this loading screen. I really do not know what to do, can anyone help?
