    Hey awesome NBR Community,

    I'm 99% certain that after three good years, the Graphics Card (9800m GS) on my Asus G50vt-X6 is going dead.

    I can't game on it anymore because within 3 seconds of a game loading, the game starts getting really bad artifacts, slows down and then ultimately freezes as big green patches occupy the screen. Only way to restart the laptop is a hard reset. The same thing happens when watching videos, but with videos I can at least watch for 20 minutes before it happens.

    I have all the new drivers, did a factory re-image, etc. but no luck. Using HWMonitor shows the GPU temps to be fine, so I don't think it's overheating. I think it's just going bad, anyone agree?

    Also, I'm now trying to find replacement GPU's. Only one I could find was this one on ebay, but it looks to be for the G71 not the G50:
    Nvidia GeForce 9800M GS 512 DDR3 MXM For Asus G71G | eBay

    You guys think it'll work on a G50? I'm guessing yes.

    Also, is there an alternative place to get the card besides some random seller on ebay?

    If the GPU is not overheating, it could be a power supply problem,
    or your graphics memory has seen better days. I haven't looked for
    one, but I bet there are graphics memory testing applications available.
    If so, you might try running one against your graphics adapter, and see
    if it reports any bad areas. To check the power theory (DC-DC supplies
    on the graphics adapter, or even on your motherboard), try lowering the
    core and memory speeds and/or raising the core voltage. If behavior
    improves, you may have a problem with the local regulators. If you are
    handy with a soldering iron, try replacing all of the aluminum electrolytic
    capacitors. Many overseas manufacturers use low grade caps. It is also
    possible that one of the support/memory chips is starting to go. You can
    test this, by running the system, and heating the board, with a hair-dryer
    or heat gun. Cold/freeze spray is also handy for this task. Lastly, you can
    try cleaning the connectors, between the graphics adapter and the
    motherboard. Sometimes dusk crawls into the gaps, and forces the contacts
    apart (due to vibration).

    By the way, does this same effect happen, when using an external monitor?
    Do you notice any odd behavior, when only running 2D applications?

    Good luck,

    Sir Robin
