Windows 7: Random BSOD in Windows 7 64 bit

Windows 7 64 bit Home Edition
Random BSOD in Windows 7 64 bit

To All,

I am new to this forum and I am hoping someone might be able to help me with an issue I have been facing for a few weeks now.

I recently updated my computer from Wndows Vista 64 bit Home Edition to Windows 7 64 Bit Home Edition.

For some reason, I get periodic crashes that can happen at any time or in any application it seems.

I managed to send someone a minidump file and they provided me with this bugcheck report but I do not know what it means:


* *
* Bugcheck Analysis *
* *

An exception happened while executing a system service routine.
Arg1: 00000000c0000005, Exception code that caused the bugcheck

Dear usasma,

Thank you for helping me and I am sorry I did not initially post correctly.

Attached please find the original minidump file.

I will look forward to your (or someone else's) response.

Not a problem. Analyzing memory dump files is a bit complicated if the cause isn't spelled out immediately.
We've got a few extra commands that sometimes pull out a bit more info.

Please update these older drivers that were loaded at the time of the crash. Don't use Windows Update or the Update drivers function of Device Manager. Please use the following instructions to locate the most current drivers:
How To Find Updated Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
Here's the older drivers:
000.fcl      Fri Sep 26 09:11:22 2008
npusbio_x64.sys Wed Apr 11 07:44:53 2007
OA002Afx.sys Fri Jun 08 04:00:36 2007
OA002Ufd.sys Tue Jun 03 05:30:37 2008
OA002Vid.sys Fri Aug 01 05:34:52 2008
pcouffin.sys Tue Dec 05 09:39:30 2006
PxHlpa64.sys Wed Oct 17 14:25:02 2007
RtNdPt60.sys Mon Dec 10 21:49:52 2007
secdrv.SYS   Wed Sep 13 09:18:38 2006
tifsfilt.sys Wed Aug 29 08:37:29 2007
timntr.sys   Wed Aug 29 08:38:23 2007
Here's a summary of the BSOD:
Debug session time: Sat Dec 26 21:38:28.549 2009 (GMT-5)
System Uptime: 0 days 1:16:01.141
BugCheck 3B, {c0000005, fffff800031ae736, fffff88005cbea80, 0}
Probably caused by : ntkrnlmp.exe ( nt!CmpAllocateKeyControlBlock+72 )
PROCESS_NAME:  dllhost.exe
If the BSOD's keep occurring after you've updated everything, then we'll run further tests.

Windows 7 64 bit Home Edition

Dear usasma,

Thank you for the advice below and this is what I have discovered:

000.fcl = Cyberlink Power DVD
npusbio_x64.sys = Track IR
OA002Afx.sys = Creative Camera
OA002Ufd.sys = Creative Camera
OA002Vid.sys = Creative Camera
pcouffin.sys = Patin-Couffin VSO Software
PxHlpa64.sys = Roxio
RtNdPt60.sys = Realtek
secdrv.SYS = Macrovision Safedisc
tifsfilt.sys = Acronis Disk Backup Software
timntr.sys = Acronis Disk Backup Software

A few of these programs I had installed on my machine at one time but have long been since uninstalled.

For those programs that remain, am I to reach out to the company's website and search for Windows 7 64bit driver updates and what do I do about those programs that are either no longer running on my pc or I am unsure what they are?

Cyberlink Power DVD - Currently on my pc
Track IR - Currently on my pc
Creative Camera - Unsure what it is, might be default software
Creative Camera - Unsure what it is, might be default software
Creative Camera - Unsure what it is, might be default software
Patin-Couffin VSO Software - Unsure what it is, might be default software
Roxio - Currently on my pc
Realtek - Currently on my pc
Macrovision Safedisc - No longer on my pc
Acronis Disk Backup Software - No longer on my pc
Acronis Disk Backup Software - No longer on my pc

Thank you and I'll await your response.

Yes any drivers you want to update go to manufacturers website to get lastest, dont use windows update or update driver option in device manager.

Any progs you have uninstalled that have left drivers behind your sure you dont need anymore just change file ext to .bak, if they do cause a problem then there still there and can be changed back if required, if not they will happily sit there doing nothing

Also some you prob wont be able to update eg secdrv.sys as this is part of software install for cd copy protection so prob wont be a standalone driver update available

kc7404 - that's mighty impressive work finding all of those drivers!

The Creative camera stuff is for a webcam. If you don't use it, uninstall it.

The Patin-Couffin VSO Softwareis related to CD/DVD burning software - so it's most likely associated with your Cyberlink or your Roxio stuff. To tell, update them and see if it updates. (FWIW - you can also download a trial of each, and then extract all the files from the installer to see if that file is in there).

To stop drivers from loading, you can use the free Autoruns software: Autoruns for Windows

To remove the drivers (if the program is uninstalled) just rename them from .sys to .BAK
This way you'll still have them if something goes wrong.
If nothing goes wrong, then you can delete them at your leisure.

Windows 7 64 bit Home Edition

To Pauly and usasma,

Thank you both for your assistance and I wanted to give you all an update.

Usasma, I appreciate the compliment you gave me concerning my homework in discovering what those files were associated with, but regrettably not all of them lead to a positive outcome in finding an implementable solution.

Cyberlink Power DVD There were no Windows 7 64 bit drivers for my program (Version 8.3.5424)
Track IR The drivers that I had (Version 4.1 build 37) are Windows 7 compatible
Creative Camera There are drivers from Creative Labs but camera specific and Dell has not
been able to tell me which model I have (It is built into the monitor itself,
software Version 1.40.05)
Patin-Couffin VSO Software I used CleanVSO.exe to remove this from my system
Roxio There were no Windows 7 64 bit drivers for my program (Version 10.1)
Realtek I downloaded the newest audio and network drivers from Dell for
Windows 7 64 (I was unsure if it was audio or network card protocol)
Macrovision Safedisc Untouched at the moment
Acronis Disk Backup Software Untouched at the moment

After I ran the CleanVSO.exe, my system did crash and some how the settings had reverted back to not saving the minidump information so I have nothing to post at the moment.

I have since changed them back to saving this information and will await a new crash to post.

My current questions are:

1) Any ideas how I might have inadvertently changed the settings back to NOT saving the crash information?
2) Do I use AutoRuns to stop those drivers that are related to programs I no longer have (Macrovision Safedisc and Acronis Disk Backup) or simply wait for the next crash to see what new information is recorded?

Thank you for your time and your assistance.

Why did it change? I have absolutely no idea! Heck, I can't even figure out why my cell phone changes like that! :) Seriously, there's a lot of different things going on in the background - so it's very difficult to even start to figure out "why".

Let's wait for the next BSOD - that way we can stop the things that are left over without having to hunt for everything.

Good luck!

I used Autoruns to stop the following:

secdrv.SYS = Macrovision Safedisc
tifsfilt.sys = Acronis Disk Backup Software
timntr.sys = Acronis Disk Backup Software

I will check today to make sure the changes are indeed in effect.

I will post again at the next BSOD.
