    ati2dvag.dll + XP service pack 2 (sp2) infinite loop Mobility Radeon 9700

    This is just impossible. My customers Vaio VGN-S1XP has XP Pro, SP2, and
    just absolutely will not start with video drivers.

    I have tried drivers from omegadrivers.net, acer (ferrari 3400), IBM, sony
    (nothing newer than those supplied on CD there).. et cetera.

    One possible solution I have read is to replace the chipset specific AGP
    driver with a generic PCI-PCI bridge driver. This doesn't work either.

    I have tried the following:

    Clean install (SP2 slipstreamed.. I don't have anything older than SP2 to
    run from), same problem.

    Removed drivers with Catalyst-cleaner thing from ATI, removed ati*.* from
    \windows , \windows\system32, and \windows\system32\drivers. Moved oem*.*
    from \windows\inf.. still the same.

    Since the PCI-AGP bridge has been suspected, I installed the latest Intel
    Inf update, still no joy.

    Have changed the system driver/HAL from ACPI to "Standard PC" .. all
    hardware re-detected. still no joy.

    The BIOS on this machine has basically NO options other than LCD-expansion
    and boot order, so there's nothing to be done in there.

    Can anybody help? Since it's SP2, Direct-X 9.0c is pre-installed.

    I'm at my wits end.

    any help wold be greatly appreciated.

    Forgot to mention that I have the latest BIOS on this machine, although I'm
    getting the impression that Sony don't do much in terms of continuing
    updates for machines once they're released.
    I am most certain this is not a hardware fault since a lot of people have
    reported the problem since SP2, and there are no display abnormalities when
    running with vga/vgasave driver.

    Which Catalyst versions have you tried? Have you tried manually
    updating the device from VGA to a Catalyst, using Upgrade Driver?

    Thanks for the reply Ian.
    For anybody googling this in future, I have decided this was a (strange)
    hardware problem.
    The customers partner had an identical machine which had SP2 on it, so I
    went over there and tried his hard drive in this machine and it showed the
    same problem. I then replaced the customers HD and it worked ?!?
    Then it crashed.
    I found it was more likely to run for a short while if the machine was
    running on battery instead of AC, so I tried some headsink compound on the
    CPU to no avail.
    anyway it looks like the machine is faulty. Just strange how it only has
    this very specific problem.

    I had tried all variances of Mobility-Catalyst drivers I could find to no

    AIR some time back the 'Infinite Loop' problem was linked to
    inadequate PSUs. This was before the current crop of cards; probably
    even before any 9xxx cards came out. I don't recall for sure, as it's
    not a problem I ever had.

    If changing your power supply from AC to battery makes a difference,
    though, it seems to me this is something you should check out.

    Just my tuppence worth, Patrick

    hey, I have the exact same problem. Did you find a way of fixing this by any chance? I have contacted Sony but as my laptop is way out of warranty they said it would cost about £650 for repair!
