    I'd suspect one of the recent Vista updates instead - I'm seeing a similar
    problem
    both on my 64-bit Vista machine, where I'm using the GPU card nearly full
    time
    to run the GPUGRID BOINC project, and on my 32-bit Vista machine, where
    the GPU is too old for GPUGRID to use it so I'm barely using it for anything
    that's heavy on it. One thing I've noted to that the problems tend to start
    when
    more that about 50% of the physical memory is in use, and most of the
    programs
    running use 32-bit mode instead of 64-bit mode (of course, the 32-bit Vista
    machine can run only 32-bit mode programs).

    My 32-bit machine probably uses an on-board video with a driver provided
    by Microsoft or HP; the 64-bit machine uses an add-in card that I bought
    from
    HP along with the machine, and an Nvidia driver recommended by GPUGRID.

    Telling BOINC that it isn't allowed to use more than 40% of the physical
    memory helps, but does not eliminate the problem entirely.

    - -"HD activity stops this
    particular file was being read/written to."- -

    Possible file corruption, or a bad/marginal area on the HD.

    If the file is much larger than any of the others, it's also possible (but
    unlikely) that the HD electronics are questionable.
    SATA cables and connectors can have a failure mode that closely matches your
    symptoms. This is usually related to vibration, temperature, and poor
    contact due to crud on the connector pins and sockets. High relative
    humidity seems to aggravate such problems. "Golden Grain" can be used to
    clean such connectors and pins. If all else fails, GG over rocks with water
    or Coke may improve your outlook.

    When a drive has a marginal area, the drive may recalibrate, and then be
    able to read an additional part or all of the file in question.
    About all you can do is try and get a duplicate good copy of the file in
    another disk area.
    An occasional defrag can help prevent some of the issues that might have
    caused your problem.

    Once you have known good backups, a Mfrs disk utility may help you to either
    identify good and bad portions of the drive, or even possibly recover the
    area that is misbehaving.
