Windows 7 STOP 0x00000051

A client's computer began halting with BSOD just after user login stage

Recent changes (late dec or early jan) include the installation of Sonicwall VPN client and Zafara email client agent

1) The safe mode (with LAN support) works fine.

2) I created a new admin user profile : but the BSOD occurs here too

3) I ran Hitman pro and Malwarebytes, both came up empty handed

4) I ran sfc /scannow ...zilch

5) I ran msconfig and booted up without loading apps or services and that worked: no BSOD

6) Then I installed logmein

7) Now I can reproduce step 5 anymore : tried disabling services and/or loaded apps using msconfig

I haven't run CCLEANER yet, but apparently it is highly recommended with this error
I am keeping from running a system restore until I have no other choice

any other ideas ?

If you disable all non Microsoft services via msconfig and everything works fine, you definitely have a third party service that is causing the problem.  I've had to do this same thing and you have to comb through the services (turn them on a few at a time) to try and identify the problem service.

I would look at your dumpfiles and see what the issue is.

You can download whocrashed and view the dump files to get a better idea of whats going on.

You could also try a system restore to an earlier time. The recommended method: Boot up in safe mode with command prompt and type rstrui.exe to restore.

i would also try running chkdsk and even using oem utilities to check the hard drive for errors (SMART, etc.)
a stop 0x51 is REGISTRY_ERROR which means there was an i/o error when reading from or writing to registry hive(s) and may not necessarily be the application itself

Hi azurtem,

As Nick Rhode's said view the BSOD to see what the culprits are. I like http://www.nirsoft.net/utils/blue_screen_view.html.

Incidentally, NetExtender did have a bug throwing BSODs on a specific version (older) but if memory serves right it was only when launching NetExtender however, NetExtender typically starts up on system boot so make sure to uninstall it, reboot and then reinstall the latest version available at mysonicwall.com. Just because you installed in late Dec/Jan, depending on how you deployed it, you could have grabbed an old version on deployment.

Also, test your HDDs - that error code has been linked to HDD faults. See this for further details: http://www.carrona.org/bsodindx.html#0x00000051

Here is a diagnostic utility to test the hard drives: http://www.carrona.org/hddiag.html

Let me know how it goes!

Thanks for all your answers

I ran Ccleaner and cleaned both filesystem and the registry

I ran whocrashed on the minidump files and ntkrnlmp.exe is the systematic 'probable cause'

I tried uninstalling logmein, and then Dell Sonicwall Netextender but I get the follogin error:

"The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance."

1) I rebooted and the BSOD was still present

2) I then rebooted a second I was however able to uninstall the apps mentioned earlier (having rebooted a second time) safemode)

3) I ran chkdsk : no errors found

4) I am restarting services and Registry RUN loaders little by little

5) no more BSOD for the moment
