Windows 7: BSOD on shutdown, irql_not_less_or_equal ntoskrnl.exe

BSOD on shutdown, irql_not_less_or_equal ntoskrnl.exe

Lately, my PC has been blue-screening after shutdown. Never during anything, but once I hit shutdown, it logs off, shuts down, and then just before I would expect all the case lights to turn off, I get an irql_not_less_or_equal ntoskrnl.exe BSOD.

From what I've gathered from Google, this is a driver issue, and the only help offered was nonspecific. I'm supposed to turn off all drivers and turn them on one by one, restarting in between, until I find the offender.

Considering the sheer number of drivers on this PC, as well as the time involved in turning on each one individually, I was hoping to get some help reading the dumpfiles for anything to point me in the right direction.

Attached is the .zip of the DM Log Collector.

Hi Rufus2468.

The crash dumps are pointing to avast! Antivirus Stream Filter driver.

Uninstall Avast using Avast Uninstall Utility. At least as a test. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Report us for any further BSOD.

Thanks Arc, that seems to have done the trick with the bluescreens.
Unfortunately startup and shutdown are still painfully slow. I think this computer has just reached its clutter limit and needs a full reinstall.

Please upload your MSINFO32.nfo file.
  1. Click on the start button
  2. Type "msinfo32" (without quotes) in the search bar of the start menu, click the resulting link. It will open the System Information window.
  3. File>Save. In the "File Name" filed, put "MSINFO32" (without Quote), give the save location to desktop, and click the "save" button.
  4. Give the time for processing, it will save a .nfo file on your desktop.
  5. Zip it, and upload it following the instruction.

Apologies for the late reply, I was away from my computer over the weekend.

Attached is my MSINFO32 results, hopefully something in there will give a clue as to what's causing the problem.

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.
Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus (you may need ot keep DisplayFusion there, too).
  5. Apply > OK
  6. Accept then restart.
Let us know if it did any change there.
