BSOD pci.sys error everytime after sleep mode Lenovo T420

Hello hdej,

► Some networking things need to be updated:

Code:

Device queue is not busy.

So we are finding two things here.

• Netwsw00.sys: Intel® Wireless WiFi Link Adapter. Update it from Customer Support.
• NETwNs64: Intel(R) Wireless WiFi Link 5000 Series Adapter Driver. Update it from Download Center.

► Again, there is Intel Rapid Storage Technology.

Code:

fffff800`00b9c868  fffff880`012552afUnable to load image \SystemRoot\system32\DRIVERS\iaStor.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for iaStor.sys
*** ERROR: Module load completed but symbols could not be loaded for iaStor.sys
 iaStor+0x2e2af

Uninstall it. It is not necessary at all, just a bundled junk.

► Have a Disc Check:

1. Reseat the sata and power.
2. Run chkdsk /f/r, following the option two of the tutorial Disk Check
3. Seatool for dos: SeaTools | Seagate download
   Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.

► Free up the startup.

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 the restart.

► Uninstall F-Secure antivirus and use Microsoft Security Essentials - Free Antivirus for Windows.

Let us know the results.

Well, first you try to update that driver, as my friend Dave76 suggests.
Support for the Intel® Rapid Storage Technology (Intel® RST)

Thanks Arc.

I would recommend the Intel RST version 11.​2.​0.​1006
There has been some issues with the latest Intel version 11.​6.​0.​1030 being unstable on some systems. Until this is verified and/or corrected you should stay with the previous version 11.​2.​0.​1006.

Can you fill in your system specs?
This would help us to research some of your issues.
This will help: Speccy Free System information Utility
Also the laptop model.
I took a guess from the info I had, is this your laptop model?
Lenovo ThinkPad T420
They have the same Intel RST driver listed on the driver support site - Intel Rapid Storage Technology Driver version 11.2.0.1006
