    Hello,
    I have a machine running RHEL 3 that crash / completely lock-up randomly. I
    think I have narrowed it down that this happens when I am running X and using
    the system for normal desktop activity (watching movie, scp-ing files, etc).
    The video card is XFX Nvidia GE Force 5200, using the latest nvidia driver. To
    be exact, this is the card that I have:
    http://www.newegg.com/app/ViewProductDesc.asp?description=14-150-042&depa=0

    The lock-up mostly happens when there's file IO (like SCP) going on. I've
    tested my RAM using memtest86 running all test for two days straight and it
    did not find any error. I've tested my processors using mprime program
    running in 'torture' mode for 3 days straight and they're fine.

    The machine would run fine for weeks or months if in runlevel 3 before, doing
    all kind of things (backup-ing / transferring Gigabytes or hundreds of
    Gigabytes of data, webserving, etc).

    So I am not sure what else to check, or how. Is it more likely a software
    problem, or the video card (hardware) problem? Does anyone have the same card
    running in RHEL 3 or other OS (ie. fedora) and can tell me their experience ?
    Does anyone know a utilities or how to stress test a graphic card ? How do I
    tell if it's more of video card problem or if it's the motherboard ? I really
    hope it's not the motherboard problem, otherwise it'd a real pain.

    Any help or suggestions would be greatly appreciated.

    Thanks

    RDB.
