I got hthe pc of my sister it was ok at first but I was watching a film on vlc and it just froze and th lines appeared, I restarted and it was fine at first then after a minute or so it happened again and then I could'nt start the pc at all so I did a new os install and now I cant update my graphics driver. Found new hardware starts every time i start up says it is gonna install nvidea 7500LE driver and then shuts down between install, I am lost for ideas. ps my other pc wont take the graphics card. thanks
