    dwm.exe, the Desktop Window Manager was involved in the crash, run SFC SFC /SCANNOW Command - System File Checker
    The dump points to the core OS file, to identify the faulting driver(s) you will need to enable driver verifier
    Driver Verifier - Enable and Disable

    Then upload the newly created dumps

    Code:
    BugCheck 7F, {8, 80050031, 6f8, fffff80002e95ec0}
    
    Probably caused by : ntkrnlmp.exe ( nt!KiDoubleFaultAbort+b2 )
    Code:
    CUSTOMER_CRASH_COUNT:  1
    
    DEFAULT_BUCKET_ID:  VISTA_DRIVER_FAULT
    
    PROCESS_NAME:  dwm.exe
    
    CURRENT_IRQL:  2
    
    LAST_CONTROL_TRANSFER:  from fffff80002eccca9 to fffff80002ecd740
    Update your SoftK56 Modem Driver from Copyright(c) Conexant Systems, Inc.
    New drivers are available from your manufacturer's website
    Code:
    VSTCNXT6.SYS        fffff880`06f03000    fffff880`06fce000    0x000cb000    0x48f69046    16/10/2008 04:52:22                
    VSTAZL6.SYS        fffff880`06eb1000    fffff880`06f03000    0x00052000    0x48f69096    16/10/2008 04:53:42                
    VSTDPV6.SYS        fffff880`07080000    fffff880`071f4000    0x00174000    0x48f69189    16/10/2008 04:57:45

    thanks for the quick reply

    i did the above steps

    enabled verifier, it then scan after reboot, asked me if i want to restore, clicked no. after its done i went to safe mode and used SFC/ SCANNOW.
    "windows resource protection did not find any integrity violations."
    i then unverified.
    where does it store the new dump file?

    i checked google regarding dmc.exe
    its the http://www.howtogeek.com/wp-content/...07/image38.png
    i use on win7. (xp-vista style quicklaunch)
    now it makes sense why i had random bsod since purchase of laptop because ive been using/tweak the old style quicklaunch since day1.
    i'll change it back to win7 style, as well as install new modem driver and see if this helps.

    thanks for the help
    greatly appreciated

    attachment is the dump file zipped
    but its not the newly generated dump file from verified and scannow though (are they suppose to create new dump file or no?)
    its the dump file from bsod, which is the only one in folder, is that the one you asked?

    These are the old dumps, wait for the system to crash a few times then upload the new dumps

    Hi aiexbadboy,

    Uninstall ZoneAlarm

    ZoneAlarm firewall is known to be a cause of BSOD's on Windows 7 systems. Download the ZoneAlarm remover. Boot to safe mode and run the ZoneAlarm remover. Reboot. Make sure the more than adequate Windows Firewall is enabled.

    Your Conexant drivers are still outdated:

    CAX_CNXT.sys Fri Feb 13 21:19:32 2009
    CAX_DPV.sys Fri Feb 13 21:24:50 2009
    CAXHWAZL.sys Fri Feb 13 21:20:54 2009 Conexant Modemor OEM
    XAudio64.sys Wed Apr 29 19:21:07 2009

    Aiexbadboy, you can try this hotfix from Microsoft if you want to keep Zone Alarm: Stop error message when you run an application that transfers data by using the UDP protocol in Windows Server 2008 R2 or in Windows 7: "STOP 0x0000007F". The fix does not always work; but you can give it a try.
