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

BugCheck 7F, {8, 80050031, 6f8, fffff80002e95ec0}

Probably caused by : ntkrnlmp.exe ( nt!KiDoubleFaultAbort+b2 )


PROCESS_NAME:  dwm.exe

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
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?

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Your Conexant drivers are still outdated:

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.
