    As it will not even work onan external monitor it sounds like the graphics is goosed!
    Onboard graphics so it could mean looking at another MB, but if your friend thinks it is worth repairing then get it to a local computer shop to check the graphics and give you an idea of what is wrong and cost of repair.

    From the top of my head these use the nvidia graphics chip, these fail very regularly in most laptops but in this gateway it has a very badly designed heatsink, the chip will need to be reflowed or reballed. In both cases it might not be economical to do unless you can do this yourself as it will most likely fail again due to the back headsink design.

    If you read up about the xbox 360 red ring of death and "reflowing" using a heat gun you could try something similar with your laptop although it is very risky and might not last that long.
