    Sound stuttering and Hibernation issues

    Hello everybody! I've been having some problems and was hoping someone might know what's going on. For the last few weeks I've noticed that my music will occasionally stutter for a few second. It's hardly noticeable but I've had the setup for a while now and this just started happening so I'm wondering if this may be a sign of something that needs to be fixed (well, obviously it does).

    Also for the last week or so I've noticed that the computer will not turn itself off after going into hibernation. It will go through the "saving your settings" screen and at the time when it's supposed to turn off, it just sits there with a black screen but the computer is still on. I just noticed this but it's has probably been happening off and on as I have noticed for a while that when I turn my car on in the morning my computer will boot as if I had turned it off instead of hibernating. Looks like my power supply cut the power when the battery got too low.

    Most of the things I've read say that the latter problem is usually caused by a bad driver or recently installed software, but I have not installed anything in a while and it was working fine for a long time, so I'm thinking it sounds more hardware related. However, one thing that makes me think it still may be that a driver somewhere got corrupted is that my blue tooth gives me an error when starting up, but I never use it so I turned it off but I am still having these problems. It's possible that something else got corrupted too, but given the stuttering audio problem in addition to the hibernation problem, hardware seems more likely (to me at least).

    Here is my worklog for details about my build, but I have the following setup:
    M2-ATX PSU
    D945GCLF2 MOBO
    2 GIGS Ram
    Laptop HDD (I forget the model)
    Windows XP SP2
    Centrafuge 2


    Ok forum, work your magic! Any thoughts would be most appreciated.

    Thanks!

    Bill

    have you tried to unplug any hardware to see if it is preventing the pc form shutting down-- like the bluetooth module?

    have you run any memory, or hdd tests to verify that the components are good?(i think this is unlikely, but it is always a good thing to check in the off-chance you have a bad sector in either that is getting in the way)

    for the audio stuttering-- if it is more like a cd skipping, check your pc's cpu usage with everything running.

    when i ran audio processing on my old 945glc, i would get stuttering audio at about 30% usage, so i had to keep my cpu-intensive audio setup under that..

    another thing you try is a DPC latency checker:
    http://www.thesycon.de/eng/latency_check.shtml

    this tool is primarily used to ensure that a pc can handle real-time a/v streaming--not extremely important here, but it can be a good tool to use to determine if a buggy driver, or component is taxing the cpu too much(my Addesso keyboard--the same one sold in the mp3car store-- causes a large dpc error about every 30 sec--without this tool, i would have never figured it out--i originally thought it was a soundcard, or wifi driver)

    Yes, although nothing funky is plugged into it; wireless mouse/keyboard receiver, touchscreen monitor, audio out.

    No, I haven't found a good free diagnostic software to use yet. I could try scandisc and see if it shows anything on the HDD but I'm usually driving when I think about it and usually not in a safe place to be playing with it. If I remember correctly XP has a memory checker, but I don't remember where and again, usually not in a safe place to go hunting for it.

    Yes, much like a CD skipping

    I'll try that too if the above doesn't show anything.
