Just a last check on my Shut-Down issue. . .

Discussion in 'Windows 64bit' started by Tony Sperling, Mar 3, 2008.

  1. Before I throw myself on the phone - anybody think it possible, even by the
    slimmest of chances, that the CMOS Battery could cause such a thing?

    The machine is about 8 months of age, and the battery could in reality be
    significantly older than that. I have not seen any other indications that
    would make me suspect the battery, I succesfully flashed the BIOS a month
    ago, but then BIOS's has been seen to have mysteriously severe impact on a
    system's apparent sanity.

    I intend to buy a second PCI-e Video Card and test that before I ship it
    off!

  2. If the CMOS data is retained the battery is good. It is possible the CMOS
    data has been corrupted, but I don't think this would cause the machine to
    shut down with no error report.

    If there is a failing component, it would probably be making electronic
    noise and this could either give misleading error reports or show up in
    unusual behaviour, though this could be almost unnoticeable. Is there
    anything even slightly unexpected about the way the machine has been
    behaving?

    Is the PSU fan running? Stalled or failed fans could lead to overheating.

    Are there any thermal cutouts in the mains power supply to the machine?
    These could be faulty or actually overloaded and resetting.

  3. Thank you. The only surprising behavior really is that it is shutting down!

    Fans are all running, but one fan has been building a rattle at start-up
    lately, I think it's the Arctic Cooling CPU fan, but it could be the Video
    Card - they are right next to each other and I cannot insert my ear close
    enough to say definitely, and Video Card fans are notoriously BAD quality!
    The rattle goes away completely after a few minutes and I cannot see that
    temperatures has been affected in any way - and I have been watching this
    for the same reason, obviously.

    Beyond that, everything looks completely normal, and just like it did since
    it was new!

    No, I didn't think it would be the battery either - I'll get another
    Graphics Card and shall see how that transpires. Like Charlie said earlier,
    it's a nice thing to have in an emergency!

    Tony,
    I would try an old trick for detecting components with marginal
    soldering/contact.
    Get one of those old wooden pencils with an eraser in the non-writing tip.
    Boot your machine into DOS via floppy with the case open.
    Hold your pencil from the writing tip (the one with carbon) and very gently
    knock (using the eraser tip) on the big capacitors in the motherboard.
    Later on continue with big-sized components, connectors, etc.
    If your PC shuts down, the root cause might be in a false contact/defective
    solder joint.
    I have used this technique when doing repairs and I have found it very useful.
    Two VGA monitors were repaired that way recently.

    Another trick for reducing your VGA card temperature.
    My new 8800GT was running rather hot.
    Default speed for its fan was 30% (aprox 900 rpm) and NVidia drivers didn't
    have any way of changing that.
    I installed RivaTuner 2.06 (works on Vista x64) and bumped fan speed to 50%.
    GPU temperature dropped 10 degrees with no additional noise from the fan!!!
