Windows 7: BSOD, windbg say caused by fltmgr.sys (fltmgr!FltpDispatch+72)

BSOD, windbg say caused by fltmgr.sys (fltmgr!FltpDispatch+72)

Hi all.
I had a BSOD today, but it's not the first.
I'm uploading the files, tried inspecting with winDBg but I have only two dmp files (cleared all few weeks ago):
The one from 09/08 says it's win32k.sys and the one from today says it's fltmgr.sys.
Tried using BlueScreenView, but no real information there (or I missed something).
Would be happy to learn how you get the right info from all those logs.

I'm attaching the rar file, hope someone could help :)
Thanks a lot.

Hello ronlut.

A fltmgr.sys error may be caused by a large range of factors, and one of them is the storage controller. And in your case it is the issue I am thinking.

Your Storage controller in use (RAID /SCSI mode) is NVIDIA nForce Serial ATA Controller, nvstor.sys; which is way old.

Updates are necessary. I dont know any right source to update it, you may search in your computer manufacturer's wabsite (GBT NVDAACPI).

At the same time, as the fltmgr.sys may be blocked by an antivirus program's filter manager driver, I would suggest you to uninstall AVG. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from, and execute the downloaded file as guided below :
  • Double click to open it.
  • Click this button only:
  • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.
Some problems are there in the display driver, too. It is also failing.

Install the 314.22 WHQL only.
  • Uninstall All nvidia items in Control Panel > Programs and features
    • 3D Vision Control Driver
    • 3D Vision Driver
    • Graphics Driver
    • HD Audio Driver
    • PhysX
    • nvidia Update
    (Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).
  • Now follow Drivers - Clean Left over Files after Uninstalling
  • Boot normally now. Go to Drivers - Download NVIDIA Drivers, Download 314.22 WHQL. While installing, Select Custom (Advanced) install. In the next page, follow this settings:

But you have to pay attention to update Nforce at first. At the same time, plan to update the BIOS too, if possible.

BIOS Version/Date    Award Software International, Inc. F9, 25/06/2007
I would request northernsoul55 to add his suggestions too; as he has deeper insight about nforce.

Let us know about your tries.

Thanks a lot for the detailed answer.
1. About NVIDIA nForce Serial ATA Controller, I found this:
Should I install this? The date is even earlier than what you stated as installed currently.
Also, tried updating from device manager but as I thought it said it's the latest driver.
2. About the graphics driver, I will update.
3. About bios, I found this:
Should I update to F11C? It says beta, but it's from 2009 and I can't find newer version.
Mine is F7 as you said, from 2007. Which one you think is safer? F11C or F10?

You may apply the BIOS, but not the storage controller, as it is older than that is already installed.

See if the BIOS update changes anything; otherwise we have to plan to omit nvstor from there.

By the way, is there any explanation for why to uncheck all those features in the nvidia installation?
(3d vision contoller, 3d vision driver, hd audio driver, nvidia update)

Mostly we dont use those stuff. What you need there in the display driver is the display driver itself and the physX. So it is better to not include the unnecessary and problematic parts.
