  1. My computer was working fine then it suddenly blacked out with a green screen. My monitor then says there is no signal. I reboot comp the letters starts to flash and my screen has green lines sometimes red, depends. Well it then keeps rebooting once I get pass the windows processing screen,

    I then rebooted the comp and it runs fine but I still have green hazy lines going vertically across my screen.

    please help,
    thanks

    I'd say the graphics card has failed.
