Bsod netio.sys

lewisrick55 · 18 Sep 2014

Hi - I recently updated a few drivers on my Toshiba Tecra R940. Since then I started to receive BSODs identifying NETIO.SYS. I rolled back the wi-fi network adapter driver, but still BSODs. I installed an earlier version of INTEL PROSet/Wireless WiFi utility, but still BSODs. Last night after the last rollback my laptop actually powered off on its own without a BSOD. I've attached the files captured by the SF_Diagnostic_Tool and hope that someone real smart can please help. Thank you.

Hi lewisrick55.

Uninstall McAfee Security Scan Plus Using McAfee Removal Tool. It is not something that you want, it came as bloated with some update from adobe.

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.

Click on the Start button
Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
Select the “Startup” tab.
Deselect all items other than the antivirus and the touchpad driver, SynTPEnh.
Apply > OK
Accept then restart.

Then (the main thing) enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip

If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any. Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Thank you - I had no idea that McAfee was installed - you are correct on how it got there. I removed it and turned on Driver Verifier. As soon as I get to a point after some important work this morning I will reboot to activate. Thank you very much for your help!

Hi - I rebooted with verifier active as instructed. This time on reboot I received a new BSOD - C1 - special_pool_detected_memory_corruption. I rebooted and then received another new BSOD - C9 with indications of PGPwded.sys involvement. My hdd is encrypted by Symantec PGP - as required by my employer.

I then rebooted into Safe Mode and disabled verifier. Rebooted normally and so far no BSODs. Attached are SF diag tool collected logs. Thank you very much for your help.

You are supposed to free up the start-up before enabling Driver Verifier.

Disable Verifier, free up startup and enable verifier again.

OK, sorry, I freed up the modules I thought were unnecessary and kept the critical ones. Later today I will follow your explicit instructions when I have some time. Thanks again.

Otherwise, Driver verifier may fail to record a crash dump, as it did.

Hi - I disabled all of the startup modules except for the touchpad (I didn't have any for Symantec). I then setup verifier, rebooted and after authenticating to Symantec PGP, I received the BSOD C9 PCPwded.sys - with no dump taken. I'll upload the SF diags anyway. I did some minimal research on PGPwded.sys and there were a few older discussions about it being a victim of the lack of memory when it loads due to a prior driver using memory beyond its allocation. I am not able to bypass PGP since my hard drive is encrypted. Thanks for any help you can provide.

As per the data uploaded in post #8, you have 32 items set to autostart with windows.

It is the third time I am suggesting you to free up startup, as stated in post #2.

If I notice no change there in your next post, too; I will not say it again, but will understand that I cannot help you, because you dont pay attention to the instructions.

Hi - apologies. The startup items were disabled at the time of the BSOD. What I had done following the failure was to boot into Safe Mode, deactivate verifier and at the same time re-enable the startup items. That is why they were listed in the diags.

This time I disabled all startups except for touchpad.
Rebooted
checked msconfig and found that two additional items were somehow configured to start - they are mandated by my employer so somehow they were automatically re-enabled; everything else was disabled though
ran verifier and activated
rebooted
received BSOD - C9 - PGPwded.sys **Note - no dump is generated in this case**
rebooted into Safe Mode
checked startups - unchanged - only touchpad and the two extra items
ran verifier and deactivated
rebooted successfully
checked startups - unchanged - only touchpad and the two extra items
ran SF diag collector
uploaded to this thread

Bsod netio.sys

Bsod netio.sys

McAfee removed, Driver Verifier set; next step - reboot

New BSODs after rebooting with verifier active

Free up startup

Another test - still no dump

Instructions followed
