windows 8 driver_irql_not_less_or_equal (Netio.sys), can anyone help me?


I've read quite a few posts about the same problem and I actually tried out some of the 'solutions' but my laptop still crashes. It crashes for an average of twice a week. 

In case you'll ask me for the minidump file, I've zipped the file and uploaded it here:

I'm not very good with computers, so I really don't know if it indeed the right file. I just went to C://Windows/minidump

About the antivirus, I had used two of them at the same time before and I uninstalled the other one, but the problem still persists. I also learned that the problem was usually caused by 3rd party antivirus and many suggested to uninstall any 3rd party antivirus and just use windows defender. I am not really sure if using your computer with just windows defender is safe though.

I hope someone can enlighten me about this matter. I'd greatly appreciate it. I've been experiencing this problem since late 2013. I have actually uninstalled may programs already.



All of the attached DMP files are of the DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) bug check.

This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.

A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses.

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.

Remove and replace Avira with Windows 8's built-in Windows Defender for temporary troubleshooting purposes:
