Windows 7: driver_irql_not_less_or_equal windows 7 netio.sys

20 Jan 2013   #1

Windows 7 64bit
driver_irql_not_less_or_equal windows 7 netio.sys

Sorry this appears to have been posed twice, my apologies.

Good evening,

I am receiving the above BSOD fairly regularly without any obvious reason as to why or while doing anything in particular. I've been having issues with my touch mousepad for a while but put that down to the buttons getting stuck in or something so have no idea if the driver for this is responsible.

I've updated all my drivers via driver sweeper and run a disc scan and the check via start button/find which scans the computer and is supposed to resolve any conflicts etc. I have also run a full Norton scan and also MBAM, spybot etc and nothing. Tried using system restore to various points but still have the issue.

I did try to post a screenshot of the BSOD but the forum said I had used too many characters - hopefully I have attached it ok. Please also find attached the windows diagnostic log as requested.

I don't really know what to look for in these logs and would really appreciate some assistance in sorting my laptop out as I need to use it every day for work.

Thank you in advance,

Welcome to SF

There are no dump files in the attachment. Please configure for small memory dumps as explained here:Netio.sys is a network error which is often caused by stubborn antivirus apps like Norton.

As a test, I would recommend uninstalling Norton and using Microsoft security essentials.

Norton tends to cause BSOD-s and several other issues. I would recommend uninstalling it with the Norton Removal Tool and replace with Microsoft Security Essentials To Test.Microsoft Security Essentials.

Recommended from a strict BSOD perspective, compatibility & stability compared to other antiviruses/internet security software. It is free and lightweight:-

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.
System Optimisers

Please remove the following software:
Advanced SystemCare 6	"c:\program files (x86)\iobit\advanced systemcare 6\asctray.exe" /autostart	NT AUTHORITY\SYSTEM	HKU\S-1-5-18\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Advanced SystemCare 6	"c:\program files (x86)\iobit\advanced systemcare 6\asctray.exe" /autostart	.DEFAULT	HKU\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
This software is a known cause of BSOD's. The windows 7 operating system does not require these registry cleaning software. They often tune-down rather than tune-up and can wreck the OS beyond repair. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Check this, this and this thread for evidence.

If you feel the need to use a registry cleaning or optimisation software, most of us recommend the use of CCleaner - PC Optimization and Cleaning - Free Download but make sure you back up the registry before making letting ccleaner delete anything.

Perform a System File Check:
  1. Click on the start
  2. Type CMD on Search
  3. Left click and Run as Administrator
  4. Type SFC /scannow
Full tutorial here:Disk Check on your hard drive for file system errors and bad sectors on it:Reduce items at start-up. Nothing except anti-virus is required plus improves the time for logging in windows.
Let us know the results.
