After two and a half years, my computer suddenly slowed down on boot up and I wasn't able to log in to my user account on Windows XP. I was able to log in to the Guest account, but it was very slow. Then the next day my computer would restart in the middle of booting up. I tried to use the recovery discs, but half way through copying the files it would crash again and again at the same point (56% of files copied). I took it into a computer repair shop and he called my back yesterday saying after looking at it that the hard drive is gone. Before I have the hard drive replaced, does anyone know if this is a correct assessment? He tried to run his own recovery tools and it would crash on him as well. Thanks.
