BSOD caused by NETIO.SYS while uTorrent running - Zip attached

Hi ozeus.

Download and install Drivers for Atheros AR9485WB and Windows 7.
Follow Driver Install - Device Manager to install it.

Let us know the result.

Yes, the driver is now updated.

Code:

    Image name: athrx.sys
    Timestamp:        Fri Feb 21 14:19:10 2014 (53071306)

But it still blames the same thing.

Code:

fffff880`037e0d28  fffff880`085b0701Unable to load image \SystemRoot\system32\DRIVERS\athrx.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athrx.sys
*** ERROR: Module load completed but symbols could not be loaded for athrx.sys
 athrx+0xc3701

So there is something else that is causing the network to fail, but not coming in the front.

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.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus.
5. Apply > OK
6. Accept then restart.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from Disk-Tools.com, and execute the downloaded file as guided below :

• Double click to open it.
• Click this button only:
• 
• If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.

Let us know how the computer is running. If the issue continues then we will take some tests.

Now 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.

Hello Arc,

my laptop was working fine in the past week, but now it just crashed. Not BSOD, but restarted suddenly.
Could you please check the attached zip?

Thanks in advance,
oZeus

P.S.: the driver verifier was running continuously trough the week.

Disable verifier. It is not needed anymore.

It seems to be a mystery now. I am failing to find anything specific that might cause network failure there.

As a test, uninstall Lenovo Energy Management. It might cause the ports to sleep which may in turn inactivate the network adapter for a while. Though it is guess only.

Let us know the result.

Can you consider a clean reinstall? If it is driver related issue then it will be minimized by it. At the same time, a clean reinstall is the best way to get rid of factory bloatware like Lenovo Energy Management. It will give you such an installation that will maximize windows native performance.
