Windows 10: BSOD kmode_exception_not_handled (classpnp.sys)

4 BSOD in the last 3 days (only 2 dump files though, don't know why). 2 while browsing in Firefox (v57), 1 while working in Photoshop CS5, the last one I can't remember which program I was using when it happened.

Each time it happened, the BSOD is there for a few seconds, then the PC reboots.

The DM Log Collector file is attached.

Any help is highly appreciated.

Kmode_exception_not_handled (classpnp.sys) on windows 10

I have had my laptop for less than 2 months. Havent downloaded any new applications or drivers and have been using it mainly for work on Microsoft Office.

3 days ago, my laptop very abruptly and out of no where crashed with a BSOD and displayed kmode_exception_not_handled (classpnp.sys). This has happened 5 times again since then.

I have run a few diagnostic tests and a virus scan however neither have come back with anything. I have also performed a full system update for windows 10, but the issue does not seem to be resolved.

You're welcome.

 

Hi Guts,

From the two crash dumps included in your log bundle, it appears that there is problem with either your hard drive or some storage drivers.

Looking at the crash dumps, I saw two 3rd party drivers that may be causing the crashes: iastora.sys (Intel Rapid Store Driver), and klbackupdisk.sys (Kaspersky Labs volume filter driver).

I would suggest temporarily removing Kaspersky anti-virus from your computer, to ensure that their filter driver is not the culprit. Regarding your Intel Rapidstore driver, you are running an outdated version so I'd suggest you update it. Here is the latest version Asus approved for your Z170M-PLUS motherboard.

You should also check that your hard disk is not failing, I recommend you run an error scan on each drive with HDTune. If you are unsure what the error scan results mean, post screen-shots of them here.

Furthermore there are many event log entries, similar to the ones below, that indicate issues with your storage hardware or the storage subsystem.

Hi Spectrum,

thanks for your reply.
I removed Kaspersky for the moment, as suggested. I guess Windows Defender will suffice for the moment?

As for the Intel Rapidstore driver, do I have to run the AsusSetup64.exe in the Driver\64bit folder to update it? Apart from GPU I'm really not familiar with the process of updating drivers.

I've run the HDTune error scan on both my internal hard drives, from what I understood they both should be fine? (see attachments) I'll also run it on the external one I've connected tomorrow.

 

Rule #4

No piracy or discussion of piracy allowed at all.
Such as software, music, videos and other intellectual property violations (e.g. downloading youtube videos locally etc) - it is forum policy that no help shall be given to people who knowingly steal software or services.

 

What a surprise...

I've been getting the exact same BSOD message (just got it the second time) and I'm also running Kaspersky's anti-virus software. I'm a Firefox user as well.

I'm attaching my .zip file too.
Maybe together we can figure out this issue! *Smile

 

Piracy was noted on your computer.
Website rules were posted in post #4.
If you remove all the piracy we can then provide help.

 

Sorry, thanks for the heads up. An officially available expired test version shouldn't be any more problem I guess.

Updated log attached, as well as the error scan of the external HDD I had connected.

 

I researched this problem a bit more and it seems to be hardware/driver problem:
Classpnp.sys Blue Screen - Microsoft Community

A few days ago I plugged in a new router and configured it and to my surprise it was still listed here
Control Panel\Hardware and Sound\Devices and Printers

I would recommend going through the list and removing the devices you're not using and see if that helps.
And updating the other drivers (video card, etc.)

 

Hello, I have the same problem as Guts and NkRQkYLz BSOD kmode_exception_not_handled (classpnp.sys) , the first time it occurred 3 days ago and after that happened several times I also using Firefox and Kaspersky Antivirus.
(and always it happens when I'm using Firefox or closing Firefox)
Did you find any solution delete Kaspersky Antivirus solves the problem or not? Here is my dmp file 120517-8984-01.zip
Thanks in advance for help .

 

I can confirm that is the case for me as well. The last time I got it I just closed Firefox.... and the time before it I was just browsing YouTube.

I opened up a ticket to Kaspersky and see if we can exclude them or not.

Waiting for a reply...

 

Same exact problem and code every time - 4 or 5 days now. Happens every day, about 2-5 times. Installed Firefox 57 probably around 2 weeks ago but had no BSODs until a few days ago (maybe an incompatible kaspersky update is the actual issue).

BSODs always occur when opening or closing tabs (or firefox itself). Only one time, it happened when I was playing an online game and firefox was open in the background.

After checking for hardware issues and reinstalling my graphics driver, I've now disabled Kaspersky and will see if this prevents it. I'll later try to turn it back on but use Waterfox (which I was using before for the 64-bit functionality).

 

I just got it a minute ago *Shock
I was just looking at my tab, reading.... Let's hope they can get to bottom of this.

 

Question for you guys - we obviously have the same issue, however my partner has the same version of Kaspersky and Firefox as me, same Windows version with same updates etc., and has had no BSODs.

So I'm trying to find out what is unique to us. Do you guys both have overclocked CPUs (perhaps 6700k)?
