Hi,
I was struggling with a random (about 5 occurrences since Sept'14) BSoD with PFN_LIST_CORRUPT code E4. As browsing throughout this site/forum and reading the acute and helpful assistance from the experts here considerably helped me out, I was willing to share back my resolution experience. I'll summarise the situation I had and provide the relevant keyword for a search to find this post. Please feel free to raise more questions on the situation I had if desirable (especially if the minidumps or screenshots of the tools are wanted or more details about my system specs).
Configuration: Dell XPS L702X laptop running Windows 7 Ultimate SP1 64-bit on Crucial SSD (C: ).
After the last BSoD I ran intense memory checks (12-16h), disk corruption checks with chkdsk and sfc/scannow, and anti-virus/malware checks (AVG, Spybot, AntiMalwareBytes). No issues found there.
The BSoDs generated mini-dump files in c:\Windows\Minidump\
By using NirSoft's Blue Screen View I could browse the minidumps and identify that the driver PxHlpA64.sys was at the root of a page fault (making it appear as if ntoskrnl.exe was the culprit).
The PxHlpA64.sys is the PX Engine help driver from Sonic. It comes bundled with various software using DVD drives, among other the Roxio Creator (which is installed on my computer supposedly to manage my DVD-RW/BlueRay drive).
Using Nirsoft's Driver View I could indeed confirm that this driver was present and loaded.
I read through this forum how to selectively prevent this driver from loading by using Autoruns from the sysinternals family of tools (filtering on 'PX' allowed to quickly locate the entry which I simply unchecked).
Once entry disabled and PC rebooted, I could check again with Driver View that the driver was no more visible in the list of loaded drivers. MSinfo32.exe also confimed in the Software Environment > System Drivers view that PxHlpA64.sys was in State=Stopped and Start Mode=Disabled).
Et voilà.
So far my laptop is stable since one day (I confess I didn't check the DVD/BlueRay drive yet -- I hardly use it -- nor did I run Driver Verifyer to stress test the laptop -- I guess I'm too happy I worked it around).
Of course, I'll get back here and add a post should I face it again.
Cheers !
