Windows 10: BSOD fault=Driver IRLQ not Less or Equal - L1C63x64.sys

    BSOD fault=Driver IRLQ not Less or Equal - L1C63x64.sys


    Have gotten a bunch of BSOD due to this problem last few days, cleared out minidump folder so there wouldn't be anything unrelated to this problem and used your program to capture the information to see what you guys could find that would help me.

    I seen a few others posted about this and we all have the same basic problem, very old driver(2013) and no official or unofficial driver to update with but saw that some of the guys had other programs that triggered the bug and the system blamed the driver and I hope this is the case for me.

    Please let me know if there is anything else I can provide you with and thanks for helping us

    Hi vaargen,

    Welcome to the 10forums.

    According to the dump there are a few drivers blamed.
    The Network In/Output system
    The NIC (Network Interface Card) driver

    My guess is that Daemon tools is the root of the problem.

    Daemon tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause for BSOD's.
    Please remove Daemon Tools and run the SPTD pass through remover.

    1. Uninstall Daemon Tools
    2. Download the SPTD standalone installer and follow these steps:
      • Double click the executable to open it
      • Click on the button shown below




    If the button is grayed out, like in the image, there is no more SPTD installation on your system, and you can close the window

    Hi axe0 and thanks for the fast reply.

    I saw when reading through the other posts that daemon tools can cause problems, so I uninstalled it yesterday with REVO to be sure to erase as much as possible from my computer and when checking with SPTD, it said it didn't find any version on my system.

    Any other tips?

    A few to start with.
    Driver verifier to get the driver that is really causing the issue.
    NTFS.sys was also flagged, but I understand that it has something to do with the hard drive.

    Please run first HDD diagnostics and driver verifier after HDD diagnostics is done

    Run SeaTools to check the integrity of your HDD. http://www.sevenforums.com/tutorials...s-how-use.html

    Do not run SeaTools on an SSD as the results will be invalid.

     DRIVER VERIFIER

    warning   Warning
    Please make a backup of your important files and get your rescue media or create one.
    Please create a restore point.

    Please follow this tutorial run driver verifier.

    Some windows drivers are blamed in a few crashes, but that usually means that a 3rd party driver is actually the cause.
    Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

    Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

    If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

    Note   Note
    Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.
