Graphics Card Failure (6600GT)

    I decided to put Vista on a spare PC yesterday. I think the graphics card
    (XFX GeForce 6600GT PCI-e) has failed but I don't want to swap it with my
    main PC without a sanity check - if the card has failed OK, but I don't
    want to break anything else!

    The order of events was:

    Install Vista - fine, recognised the card and ran both monitors.
    nVidia have just released a driver update for Vista so down-loaded and
    installed it, again it worked.
    I then installed and started 3DMark03 to benchmark it, left it running and
    went off to do something else.
    When I came back the screens were covered with unreadable characters, with
    the Vista desktop just about visible underneath.
    I re-booted the PC, still the same including an unreadable POST screen.

    I took the card out to check and re-seat it, re-started, the fan is
    running OK but still no intelligible display.

    I have put a Matrox Millennium PCI card in and the PC runs OK with that
    (bloody good work horse card, a hundred years old but still going strong!).

    My main PC uses the same card so I could swap it to check but I am
    concerned that it may cause damage to that PC - but I think it's the only
    way I can check it.

    Logically it seems it's not a driver issue (or POST would look OK) so
    either the graphics card has failed - or perhaps the PCI-e slot on the DFI
    mobo has failed. I think also it's not a RAM issue or the PC wouldn't work
    with the Millennium card .

    Any thoughts would be appreciated, I think I have to swap cards to check
    it but I do not want to blow up my main PC which is a newly built Intel
    BadAxe board with an E6600 on it!

    It's completely dead now :-(

    I bought a new ATI cheap card for now, I'll wait for DX10 to become a bit
    cheaper before I go for a better one.
