    Here I guess you want a new screenshot.

    Changing the monitor doesn't effect anything.

    video memory fails

    and chess-like screen because of video memory tiling.

    mac pro 3.1 xeon processor

    We've tried both graphic card (ati 5870 graphic card and ati 2600xt) But we got same problem as always.

    And near time we did change the ram kit also.

    ----------

    I'm thinking it could be the motherboard the guilty. because this is the second time we are changing the ram kit and third time changing the graphic card.

    Have already tried reinstalling the system?
    If you hold CMD and R while booting, you should get into the recovery partition. Are you seeing the problem there as well?

    If so, try another PCIe slot.

    Without a picture I'm really guessing, but I'll try guessing something that hasn't already been mentioned.

    Dirty keyboard? The keys pressing onto the screen while it is closed, leaving a faint 'chessboard' like pattern.

    just guessing

    I thought for sure it would have been the graphics card, but as you say, you've replaced it twice now. I would try a different monitor, different video cord, and different PCIe slot.

    :p Mac Pro, not MacBook Pro.
