Windows 7: BSOD "Pool_Header" - help analyze DM Log Collector info

BSOD "Pool_Header" - help analyze DM Log Collector info

Hi guys.

I haven't added any new software or hardware to my system recently. Yesterday, I started getting the BSOD either before or after I click on the Profile to use and it starts loading the little icons in the lower right corner (system tray?). The BSOD is only on the screen briefly and I can only make out "Pool_Header" and ID of 19 as part of the problem.

Here's what I've tried so far:

1) The problem happens in both profiles on my system.
2) I can log in with Safe Mode every time. No problem.
3) My antivirus hasn't indicated any problems.
4) I ran the Windows Memory Diagnostic and it found no problems.
5) I did chkdsk and it found no problems.
6) I used my Ubuntu (Linux OS) Live USB for awhile to possibly rule out failing hardware as an issue.
7) Windows 7 Startup Repair could not detect any issues.
8) I have a backup of my non-Microsoft drivers and restored them. It made no difference.
9) I did a System Restore to an earlier restore point from several weeks ago and it still occurs.

As a last resort, I am now asking (begging) for your help.

If it would help, I have two of this exact model computer. Both systems are set up the same. If it's a Microsoft driver, maybe there's a way I can copy them from one system (not sure where they are) and write over them in the problem one? Just a thought.

I've attached the DM Log Collector results. Thank you so so much.

Here's an update: I found out about an online service called OSP Online. You upload your dmp files to it and it analyzes it and tries to identify the driver causing the problem.

In my case, it points to aswSP (aswSP.sys), the Avast self-defense module and driver.

I did some more Googling and found out I can uninstall Avast from safe mode with a tool they offer called Avastclear -

Does this seem like a safe approach? Uninstall Avast in Safe Mode, and then try reinstalling it in regular mode if that clears up the BSOD?

Hi Sonic,

Uninstalling Avast is the way to go during troubleshooting

looking at the other reports, (DUMP's not my area)
GWX is no longer required uninstall it.
Your system has not updated since 2015 appears to be a network error. BITS has been dissabled AND
Because of this your only line of defence is the pre-installed Windows Defender - OUT OF DATE
please try and install MS Security Essentials
Can you tell me what version of Netframework your running if its out of date and i suspect it is anything dependent on it will fail.

I dont think GWX dissabled BITS, so did you?? if so what else!!
Please update your system
and if/when your next BSOD occurs post a new set of logs.

Hi torchwood. Thanks for your help. Good news! I uninstalled Avast with Avastclear and re-installed the newest version of Avast. It looks like that fixed it. re: BITS & GWX ... I purposely took drastic measures in 2015 to prevent my system from upgrading to Windows 10. I installed GWX Control Panel at that time. I don't want Windows 10 under any circumstance. My defense has been Avast, privatefirewall, AdBlock Plus, NoScript, spywareblaster, and various backups. I've never had a problem. I love Windows 7 and will keep it for as long as I can, and then I plan on switching to Ubuntu Linux. I've been running Ubuntu for a few months from my external hard drive to become familiar with it. Can I enable BITS and Windows Update again without being forced into Windows 10? I'll look into that if you don't know. Thanks again for the help. This is a great forum.

Hi Sonic,

ALL of the W10 nag updates have been pulled, so go ahead an ENABLE BITS & turn on WU, from what i saw in the logs there are quite a lot of updates you require.

NOTE there as still some minor OPTIONAL updates that try to get you ready for W10 but just hide them. ALSO CREATE A RESTORE POINT NOW, just in case
SET WU to let me choose ignore ALL optional and any Preview ones in recommended.

Should set you up and running.

Have a look at Linux Mint, in my opinion better than Ubuntu

It appears re-installing Avast solved my problem. Everything is still working, so I'll mark this thread as Solved. Thank you torchwood for your help.
