Windows 7: Sporadic BAD POOL HEADER BSOD

21 Aug 2012   #1

Windows 7 Home Premium 64-bit

Our 2 year old Dell has been throwing Blue Screens for about 2 months now with no (seemingly) consistent rhyme or reason. One day it happens while browsing in IE or Firefox, other days you walk in and see the computer has rebooted on it's own.

I've found and turned off the automatic reboot, so hopefully will have more screen details soon. But in the meantime, I have run the SF Tools. Hoping for some guidance, thanks in advance!

Tried the suggestions, as well as going out to the Dell site to get list of any other vendor recommended updates. Dell even had a BIOS update out there. Unfortunately, when I applied this I lost internet for a few days before I was able to use my wife's iPad to find a fix.

So, things had been running ok for a bit - I even thought the BSODs had stopped as the wife hadn't complained.

Well now they're back again - I've BSODed 3 times just trying to get this file created. Any other recommendations? Do I have bad memory or GPU? (By the way, the previous link talked about NVIDIA, but we've got ATI.)

bckd.sys - Try the following:

You have a bckd.sys which is K9 parental web filter. Could you uninstall this?
The web filter is taking from K9 Web Protection - Free Internet Filter and Parental Control Software | Free Internet Filtering and Parental Controls Software, does this look familiar?

After the uninstallation, go to the path (\SystemRoot\system32\drivers\bckd.sys) where the driver was supposed to be, and make sure it's gone.

Please uninstall McAfee. Its a known cause to BSoDs.
Download and install MSE, run a full scan after updates are done.
Microsoft Security Essentials - Free Antivirus for Windows

Then run the system file checker, run more than times if it finds files to repair.
SFC /SCANNOW Command - System File Checker

For now, do this and report back. If you still get BSoDs, we'll do more troubleshooting.
