    BSOD on closed down and start up

    Hi guys
    i am new to this forum but i am fed up with the constant error messages since i upgraded to Windows 8.
    I have run through several of the suggestions posted here but to no avail.
    I have followed the instructions regarding the SF thread and will upload the zip file created.
    I hope the contents make sense to someone!
    Thanks in advance.

    Extremely old Driver

    Welcome to Eight forums.

    Looks like an extremely old driver of your Conexant Modem is the cause of the bsods. Please update its drivers.
    If no updates are available, please stop using the modem and uninstall the software. See if the BSOD problems persist.

    information   Information
    download and install Revo Uninstaller.

    • Opt for "Advanced Mode" and uninstall the software (also delete the leftover registry entries).

    This is a very common bugcheck.  Usually the exception address pinpoints
    the driver/function that caused the problem.  Always note this address
    as well as the link date of the driver/image that contains this address.
    Some common problems are exception code 0x80000003.  This means a hard
    coded breakpoint or assertion was hit, but this system was booted
    /NODEBUG.  This is not supposed to happen as developers should never have
    hardcoded breakpoints in retail code, but ...
    If this happens, make sure a debugger gets connected, and the
    system is booted /DEBUG.  This will let us see why this breakpoint is
    Arg1: ffffffffc0000005, The exception code that was not handled
    Arg2: fffff88003ac307e, The address that the exception occurred at
    Arg3: fffff880009b7968, Exception Record Address

    Thanks KOOLKAT77

    Yes that has cleared my constant BSOD issue thank you very much.
    However start up now seems slower and I didn't use the revo uninstaller as it didn't show up, so I guess the registry entries are still there.
