Windows 7: BSOD after updating Nvidia drivers

24 Aug 2013   #31

Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

Ok, I ran verifier all day yesterday and had no crashes, however today I got another memory_management crash whilst playing GW2 (verifier was DISABLED).
Minidump attached. I might run verifier again and leave it on for longer.

Report back on the findings of Driver Verifier, we may need a Kernel Memory dump.

I've run driver verifier all day and have had no problems. Is there a way to tell if it is running?

When opening it again and checking "Display information about currently verified drivers", all of them are loaded apart from nvbridge.kmd which is "Never Loaded".

This has the description "NVIDIA Compatible Windows Vista ..." (can't see the rest), when I go into "Display existing settings".

Hope this information can be of some use.

To see if Driver Verifier is running, then open a elevated command prompt, and then type this command:

verifier /query
Also, we may now need a Kernel Memory dump instead, we will retain all the Kernel Mode address space at the time of the crash. Upload the file to a file sharing service such as Skydrive and Dropbox (both which provide free space), and then ensure you upload the file to the Public folder of your account. Once completed, then post the URL of the file in your next post.

Ok, it looks as though I already have it set up by default to produce a kernal memory dump. I assume I should just wait until I blue screen again and then grab the file?

Yes, when a another BSOD happens, then follow the above procedure, by default, it should be saved here:

Is there any at the moment?

Ok, just got another blue screen then, this time it was a new error PFN_LIST_CORRUPT I think. I've attached the minidump and I am uploading the MEMORY.DMP now, I didn't realise it was so large!

Edit: Finished uploading, here is the link:

Usual causes:  Device driver, memory

The reference count is not below zero, therefore I believe the problem is not a result of incorrect MDL handling. The physical page, seems can be shared between multiple processes if I'm correct, and is currently located on the Standby list which is allowed. The reason for the crash, could be drivers referencing memory addresses which they do not own.

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:
information   Information

I understand we have ran Driver Verifier before, but this time enable the previous settings with the addition of the Special Pool setting. This is important, because it changes how Windows allocates pages to processes and drivers, each driver is given it's own page of memory instead of having a page shared among different drivers. This setting will be more memory intensive.
