    Ok here are my specs
    Power Mac g5 dual 1.8ghz pci-x
    8 gb ddr ram
    two 1.5 TB hard drive
    wifi card installed
    nvidia mx5000 standard graphics card

    Here is the issue
    When I boot and press "option" to select a hard drive or disk everything looks fine
    but when I load into either the OS or a OS install disk there are long light green lines going from the apple all the way to the right end of the screen in a straight line.
    And when it boots most dark colors look fine , but in white boxes and at the top menu bar there are either long light green lines or very small to large green blocks , they are translucent but they are there.
    I have done everything I can think of.
    Ive re installed the os, re seated the graphics card
    re seated all the ram. PMU reset, Pram reset, ran hardware check from the os disk, ran tech tools pro , EVERYTHING nothing helps.
    I think it may be the graphics card.
    Can I get any input?

    You think right. Replace it.
