    Hello all,

    Uninstall any Cfos software you have. Here is the module that is causing the BSODs, and it comes from Cfos.
    Code:
    cfosspeed    cFosSpeed for faster Internet connections (NDIS 6)    c:\windows\system32\drivers\cfosspeed6.sys    Kernel Driver    Yes    System    Running    OK    Normal    No    Yes
    Also Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.

    1. Click on the Start button
    2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
    3. Select the “Startup” tab.
    4. Deselect all items other than the antivirus.
    5. Apply > OK
    6. Accept then restart.

    Let us know for any further BSOD after doing these two.

    SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
    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
    happening.
    Arguments:
    Arg1: ffffffffc000001d, The exception code that was not handled
    Arg2: fffff88000000028, The address that the exception occurred at
    Arg3: fffff880048afdd8, Exception Record Address
    Arg4: fffff880048af630, Context Record Address
