Hello all, my laptop BSOD'd last night for the third time this month, so I'm hoping you guys can help me out. I bought this laptop (Lenovo ThinkPad T420s) two months ago, used (it's a couple years old) and put my own hard drive in it, reformatted it and installed Windows.

 

 

Windows 7 Professional x64

Service Pack 1

Intel core i7-2620M CPU @ 2.70GHz

8GB RAM

 

I didn't write down the details from the first two BSOD, but the last one said "DRIVER_IRQL_NOT_LESS_OR_EQUAL." Technical info in the spoiler.

Spoiler

 

I'm having trouble uploading files, so I'll post the minidump debug of my most recent BSOD under a spoiler tag.

Spoiler

And the debug from the BSOD two days ago:

Spoiler

 

Below are some of the errors/warnings from Event Viewer from around the time of the last BSOD. (There are so many error/warning messages I can't post them all)

Spoiler

 

As I shot in the dark, I replaced both of my memory cards with a single 4GB memory card which I know is good. So far, no BSOD (though I wouldn't expect one) but I'm still receive the same errors/warnings in Event Viewer (which I should excpet since none seem to be memory related anyway)

 

The BSOD's happen randomly, and I'm only ever running qBittorrent, notepad (or TED notepad), and Firefox (with probably a million tabs open).

 

 

Thanks so much for your time! Let me know if you need anything else.

Ana

Hi

 

NETwNs64.sys is the driver file of your Intel wireless adapter. Event log also shows WiFi related errors.

Warning 3/16/2014 8:39:56 PM Microsoft-Windows-WLAN-AutoConfig 10002 None "WLAN Extensibility Module has stopped.

I would recommend updating your wireless driver. Uninstall the old one ( Intel PROSET wireless ) and try installing the below version.

You should minimize the number of tabs in Firefox.

Thank you, I uninstalled the old proset drivers and installed te new ones. I just re-started my computer, but I'm still getting error logs in Event Viewer.

Spoiler


I'm looking at Device Manager right now, after installing the new drivers, some devices under "Network adapters" have changed, which I think is normal. My wireless card "Intel Centrino ...." is listed twice though, once under Network Adapters and again under "Other Devices" with a yellow warning sign by the icon. The one under "Other Devices" says "The drivers for this device are not installed," and when I select "Update driver" it cannot find the correct driver. The other Intel Centrino adapter under Network Adapter is working fine though, with the newly installed drivers. Should I disable the second one?

The one under "Other Devices" says "The drivers for this device are not installed,"

 

It means your WiFi card came with dual functions -probably it will be a WiFi + Wimax adapter. In that case, please choose the correct model from the drop down menu and download the appropriate driver.

Hello Anshad, I just had another bluescreen. It was caused by NETwsw00.sys, the wifi driver that replaced NETwNs64.sys which caused my previous blue screens.

 

You are right about the WiFi + WiMax dual function, but for some reason I was not able to get the driver for the WiMax function to install from the website (It's the same PROSET driver set). 

 

Here is the minidump debug

Spoiler

 

Do you think this might be a hardware problem instead of a software problem? Could it be a problem with the wifi adapter itself?

It is Intel® Centrino® Advanced-N + WiMAX 6250

 

Thank you so much for all your help so far

Please try the below steps to find a pattern.

 

1. Since generic drivers from Intel is not fully functional, please uninstall it and download the driver from your system manufacturer's website. Make sure both WiFi and Wimax installed properly.

 

2. Delete  or move all the crash dumps from "C:\Windows\Minidump" folder. 

 

3. If BSOD continues with the OEM driver also, try to find a pattern. For example you might be getting BSOD only when downloading torrents or using Chrome , Skype etc. Try to reproduce the BSOD by running a specific app.

 

If you can't find a pattern, zip and upload all the crash dumps ( minimum 3 ) with next reply.
