BSOD when logging off - happens about every 6-8 logoffs

rbhall52 · 20 Jun 2018

My wife's laptop, an ASUS A54C, has been experiencing periodic BSOD screens when logging off. I recently rebuilt the operating system using the recovery partition, and the BSOD screens, which were happening before the rebuild, started happening again, just not as often. At this point, they are happening about every 6-8 logoffs. I did not actually count the logoff to determine this number, but it seems about right.

I downloaded and ran your dmlog collector program, so I am including that zip file with this message. The date of the rebuild should mean the data from the last 2-3 minidumps is the only data you should need to look at. Hopefully, you can make some sense of the minidump data and find the cause. I assumed that the cause was a driver, and it may still be, but since it is only happening during the logoff process, that might change what the cause might be. Thanks for your help in advance.

I am pretty experienced with windows 7 and computer programming (fortran iv, C, assembly language), so I will have no trouble following any help instructions you might have for me. I also happen to have an EE degree under my belt, which has helped over the years when programming to control different devices. 'Nuff said :).

Hi rbhall52,
Nice credentials!

Attachment 404346

The SESSION_HAS_VALID_POOL_ON_EXIT bug check occurs because a session driver does not free its pool allocations before a session unload. This bug check can indicate a bug in Win32k.sys, Atmfd.dll, Rdpdd.dll, or a video or other driver.

Admin CMD run sfc /scannow, may have to run it two or three times to repair system files.

Check your video and other drivers for corruption and updates.

Hi rbhall52,

Do you have experience with debugging (in kernel mode, with x64 assembly)?

As Snick suggested, check for corruption and Windows Updates, and update or reinstall the display drivers.
This crash happens to be a very rare one, you're the first I've ever seen to get it. I would almost request a memory dump, but I'm not very well with memory debugging.
@Snick, it would be better to use the sevenforums driver verifier tutorial, because the part with selecting the settings is for Windows 7 different than what your link shows.
Driver Verifier - Enable and Disable - Windows 7 Help Forums
Also, I wouldn't recommend using sites where driver update software is used, especially with BSODs it's important to provide the right sources for drivers.

Thanks for your input AxeO. Always a leaning experience reading your posts! Will note your recommendations. Now that I think of it, I remember you making that point on another thread.

Rare one, explains why researching provided very little insight!

Have a Great One!

I'm not entirely sure what happened, but after I did the windows recovery procedure to put my wife's computer back to a previous date of operation, I have not seen a BSOD when logging off since. I did the recovery because I saw a BSOD that mentioned a file used by PrivateFirewall and it seemed to indicate a problem with the file. So I deleted the file and started having problems with PrivateFirewall. Things were going south, so I did the windows recovery procedure. I guess that must have been around July 1, because I checked the windows logs and that is about the day after which none were logged. My guess is that some corrupt files, whether drivers or otherwise, were replaced, and the BSOD's seem to be gone. Hopefully, that will stay fixed and I can move on to figuring out how to get the usb port on the left side of the same laptop working. I may have to go ask the question or check forum questions to see exactly how to roll back the usb driver to it's original state and start over with it.

Thanks for everyone's help with my BSOD problem, and may no one have this problem again, including me :).

Glad to hear

Snick, many of the hundreds of BSOD crashes are rare in a sense that you will only see them when developing software. If you can't find info on a crash, it's very likely a rare one in such a sense.
