Windows 7: Bsod bad_pool_header

Bsod bad_pool_header

Hi there. A few days ago my wife locked her computer with control+alt+delete, Lock this computer. Then she turned off her wifi. When she came back to the computer it had a black screen and she was unable to log back in to Windows. She did a hard restart and the BSOD appeared with the BAD_POOL_HEADER message. Since then I've been able to restart it in Safe Mode only. When in Safe Mode, I went into msconfig and reduced the apps and services that fire up on start up down to those from Microsoft, Intel, and Sony thinking that it might help but it hasn't. I tried using a repair disk but that didn't work.

I used the dm log collector to make the attached zip file. Any help would be greatly appreciated.

As an aside--November 2013 was the last time that her Windows updates installed successfully. Since then, they've failed to install. She tried manually installing the Windows updates but was unable to.

Also, for the past couple of years the screen would freeze once a week or so and she'd have to restart the machine to be able to use it again.

Boozad, that worked! I used the download to remove AVG. After that, I was able to start Windows normally. Then, I removed a couple of other AVG programs that were left over. There was an installer that was being stubborn about being removed.

I installed Windows Security Essentials. After that, I was able to successfully install a backlog of 31 Windows updates.

I aslo installed Malwarebytes--it's running now.

I'm creating a back up disk now as well.

Thank you so much for your help!


NoelDP, I did as you instructed and here are the results. Do you see anything? Thank you for looking.

There should have been a lot more than 31 uodates to install! Do another Check for updates and see if more appear. If not, post the c:\windows\Windowsupdate.log file
