Could this be a CPU bug?

    Hello.

    My computer is having this chronic problem which I believe is hardware
    related. I've narrowed it down to either the CPU (Athlon Thunderbird 850
    socket A) or the motherboard ( Asus A7V133-VM, VIA KM133 chipset)
    The problem happens at random, but is more commonly 'provoked' when
    there are sizeable numbers of bitmaps being held or loaded into memory,
    by this I mean things such as icons in software, loading a webpage with
    lots of pictures, etc. The application then quickly leaks 100s of mbs of
    ram until it runs out of resources (things go black & white or fail to
    display) & crashes. I think this is an issue related to AGP. Software &
    video cards are not the issue.
    Is it possible that this could be being caused by the CPU? I've read
    about some AGP bug affecting Thunderbirds when processing 3D, but this
    affects 2D only.

    Any help appreciated (I am tired of faulty hardware).

  2. What OS do you use?
    I used to have this all the time with Windoze ME (and sometimes, yet, not as often with 98).

    how do you know that this isnt a software issue?..
    now.. for the data to be continally pushed to the ram in a loop then I would
    say "if" there is a problem then it's with the motherboard..

    Personally I think it's a software issue (no matter what microsoft tells
    you)

    It sounds like it is software to me... I mean the hardware doesn't know if
    you have bitmaps in memory does it?

    Do they start out as bitmaps or GIFs? Or JPEGS?

    I would suggest that this is a software problem related to the image
    decoder - maybe a corrupt dll

    How do you know it's not faulty software? If you were a software engineer
    you would know that you simply cannot be entirely sure that there are no
    faults in software. And if you are not a software engineer you would be
    hard pushed to attempt to diagnose it.

    Yes, so I want to know if he was using one or the other. Why did you
    post that?

  11. I have a Gigabyte 7vtxe which I've had for about 2-3 years. still use the same mobo and since I've changed to win xp I have no
    probs. still use the same 1.5 gb ram as well.

    Same KT/KM chipset, so VIA's infamous 'Q.A.' department is to blame... an 'upgrade' to WinXP would cost me $500 and stop half my
    programs from working... maybe I could swap this motherboard with a WinXP user I know's 100/200fsb motherboard.

  13. This problem may also be with some programs running on your system since I've seen other win 95,98,ME users with no apparent
    problems. I, however run all kinds of apps on my system for all different sorts of things. If theres a way for you to evaluate what
    apps you run, that may be helpful also. Maybe disable some of those "Start with windows" apps and only start them when you need. I
    agree with the other posters here that its more than likely a software issue. Its either your OS or some of your apps or both. Good
    luck and I hope this helps.

    No question. Between the two the via chipset is the known flakey part.. If
    you're tired of hardware problems, stop using Via chipsets!

    Hello.
    Gawd..
    If you support the fact that this is probably a hardware fault then you
    probably dont have what it takes to get a VIA system stable...
    Nvidia systems arent as bad to get stable with driver issues, via problems
    can be hard to fix but can be fixed. He has a software issue, Maybee he's
    running some p2p app or icq or just SOMETHING that's causing some really
    buggy stuff to happen. Norton av can cause these types of problems, Norton
    firewall can cause the same problem with connections that dont get reset (ie
    telnet connections). Dont support a flawed statement with another flawed
    statement.. that's just wrong

    With a clean install of Windows 95 or ME on a brand-new clean hard-drive with no
    other drivers or software installed and no hardware such as modems and sound
    cards installed, with different ram modules & PSUs tried, this still happens.
    Unless Matrox, nVidia and S3 all produce multiple revisions of video drivers
    with the same identical bug in them, then this is not a software issue unless
    the issue is with Windows itself. If Windows 9.x has got a software display bug
    in it, then VIA's & / or Asus's Q.A. should've noticed and worked around it, but
    I'm guessing they may've never done basic stress testing under anything except
    Windows NT/XP.
    I wondered about a CPU bug being at fault as it is a fact that AMD Thunderbirds
    have graphics-related bugs which have been known to cause lockups.

    Okay,
    What "Known fact" of thunderbirds and graphics? .. I got one that's still
    running today (athlon 800) and I have never had this problem..

    now.. What are you using to "view" these graphics? ..
    I mean is it any graphics program or just specific graphics programs, or
    just internet explorer..

    Did you try upgrading your directx version..

    Did you check for video card updates, did you try older via drivers, newer
    via drivers. VIA drivers can be flakey, try older versions, try newer
    versions, Did you check your RAM settings (ie turn them down).. Try running
    memtest for a day or so and see if you have any failures..

    I am not saying a hardware failure is impossible or that the cpu is faulty
    BUT.. I find it verry odd that your using a motherboard and processor that's
    ? 3 or 4 years old now.. and this is the firs time a fault like this has
    been mention'd

    FWIW,
    Test your AMD processor for false pixels with JPEG or MPEG videos

    That problem seems to be with jpeg images not being displayed correctly

    but it's def not what this guy is reporting

    A stable Via system is an oxymoronic statement as they are only stable
    because the owner hasn't pushed them. And who in their right mind WANTS to
    play with new/old versions of 4in1 drivers trying to get flakey hardware
    stable when there are OTHER options that don't require these hassles?
    What's the point in shooting yourself in the foot when you KNOW it's going
    to hurt? Oh I see YOU buy Via boards and fight with them? LOL!! "Gawd" help
    you!

    If you read the OP's statement this sounds like flakey hardware to me. $20
    says put this chip on an non-via board and the problem will disappear.
