Q: Blue Screen with IRQL_NOT_LESS_OR_EQUALin Windows 7

After many blue death screens with this error message, Windows worked in Safe Mode, but crashes in Normal Mode. I uninstalled two questionable drivers to no avail. I uninstalled Norton 360 so now the machine tries to boot Windows but freezes. Hardware diagnostics are all OK except for a failed SMART test of the HDD. Here are the dump files:

I'm at my wit's end and cannot afford to waste more time with this, so please help!



My pleasure!

If and when you are comfortable and feel your issue has been solved, I'd recommend marking any posts of mine that answered your question as answered so this thread no longer shows up as requiring an answer.


Nope, they were likely false positives. Don't worry about it unless you start seeing actual problems that are leaning towards a faulty HDD.

If you'd like to be extra sure just for your own peace of mind, you can run Chkdsk + Seatools:

There are various ways to run Chkdsk~

Method 1:

Start > Search bar > Type cmd (right click run as admin to execute Elevated CMD)

Elevated CMD should now be opened, type the following:

chkdsk x: /r

x implies your drive letter, so if your hard drive in question is letter c, it would be:

chkdsk c: /r

Restart system and let chkdsk run.

Method 2:

    Open the "Computer" window
    Right-click on the drive in question
    Select the "Tools" tab
    In the Error-checking area, click <Check Now>.

If you'd like to get a log file that contains the chkdsk results, do the following:

Press Windows Key + R and type powershell.exe in the run box

Paste the following command and press enter afterwards:

get-winevent -FilterHashTable @{logname="Application"; id="1001"}| ?{$_.providername –match "wininit"} | fl timecreated, message | out-file Desktop\CHKDSKResults.txt

This will output a .txt file on your Desktop containing the results of the chkdsk.

If chkdsk turns out okay, run Seatools -

You can run it via Windows or DOS. Do note that the only difference is simply the environment you're running it in. In Windows, if you are having what you believe to be device driver related issues that may cause conflicts or false positive, it may be a wise decision to choose the most minimal testing environment (DOS).

Run all tests EXCEPT: Fix All and anything Advanced.

All of the attached DMP files are of the IRQL_NOT_LESS_OR_EQUAL (a) bug check.

This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.

This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high. The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.


By default, the fault of the crashes is NETIO.sys which is the Network I/O Subsystem. This is not the true cause of the crash, and usually when we have network related crashes like this, it's caused by one of two things:

1. Network drivers themselves need to be updated.

2. 3rd party antivirus or firewall software causing NETBIOS conflicts.

Also, in some dumps, we even have Norton in the stack:

You noted you removed it, but I still see quite a few remnants listed and loaded in the modules list. Please run the removal tool:
