Dell laptops bluescreening when using usb kensington adapter

[thomas159]

Hi,

I have around 5 dell laptops that have been blue screening recently it looks as if it is the graphics drivers but these have all been updated and it still continues to bluescreen.

I have attached the dump files as well as some other files

Anjy help much appreciated!!

OK had a look through your dump files and a few things stuck out at me:

First please install service pack 1:

Learn how to install Windows 7 Service Pack 1 (SP1)

next please update the following driver it seems to be causing all sorts of problems as it is present in almost all of your dump files:

fffff880`061b29b8  fffff880`04157000Unable to load image \SystemRoot\system32\drivers\dlkmd.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for dlkmd.sys
*** ERROR: Module load completed but symbols could not be loaded for dlkmd.sys
 dlkmd

Driver Reference Table - dlkmd.sys

please update the driver from here: DisplayLink: Windows Software!

Thanks for the quick reply,

I'll get SP1 Installed and I have updated that driver to latest version but might try putting an older version on and see how that goes.

I look forward to your results.

In addition, you'll be better off by uninstalling the software below. (If not permanently, then as a test):

Start Menu\Programs\Check Point	Public:Start Menu\Programs\Check Point	Public
Start Menu\Programs\Check Point\Endpoint Security	Public:Start Menu\Programs\Check Point\Endpoint Security	Public
Start Menu\Programs\Check Point\Endpoint Security\Troubleshooting	Public:Start Menu\Programs\Check Point\Endpoint Security\Troubleshooting	Public
Start Menu\Programs\Sophos	Public:Start Menu\Programs\Sophos	Public
Start Menu\Programs\Sophos\Sophos Endpoint Security and Control	Public:Start Menu\Programs\Sophos\Sophos Endpoint Security and Control	Public

• Download and install Revo Uninstaller free from here: Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

Opt for "Advanced Mode" and uninstall the software (also delete the leftover registry entries) then, reinstall the latest version available from the mfg website or a good source like filehippo.com
​

• Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.

• Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7 . The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

Your DisplayLink Core Software seems to be outdated and causing problems, update it from here:

• DisplayLink: Windows Software

Other portions of the software must be downloaded from the OEM.

The OEM will be the brand of your computer, visit the support page for your model, to download and update the other parts.

EDIT: I'm too slow
