    vwifibus.sys crash on shutdown?


    Hi there I've basically had this crash since i built my windows 8 computer at the end of last year just never really got round to fixing it as it only happens several times a month and once it restarted it shutdowns nicely anyway. so its not been too much of problem finally trying to fix it.

    the problem is my computer crash's sometimes 5-6 mins after the shutdown button has been hit. and restarts itself.

    I've used the debugging tool via cmd to sort through my dump and mini-dump files. dump didn't really have anything in but the minidump seems to have found the problem regarding "driver power state failure" which is what the bsod is.

    its seems to be a problem with a file called :

    vwifibus.sys can someone please verify that i am correct?

    i've attached my debugged log. hopefully I've done all the hard work for you

    Unfortunately, it's not quite as simple as that.
    First off, the actual cause is rarely a Windows driver. In fact, well in excess of 90% of BSOD's are due to 3rd party drivers (ref: Windows Internals v5 and v6). After that the most common cause is hardware problems, and lastly are Windows drivers.

    What often happens is that the offending driver writes to a section of memory that another driver owns. Then the offending driver exits - so there's no trace of it on the memory stack. Then the other driver goes to look at this memory location and panics because the info there is wrong - and it crashes. Yet there's no evidence left as to the original driver.

    But, we can draw some conclusions from this. That is that this is a networking error, and may also be a wireless error.
    This means that it's something that's using the networking - and maybe even the wireless connection drivers memory space.

    If you have a wireless, USB network device - this may be a cause. Here's my canned speech on them:
    I do not recommend using wireless USB network devices. Especially in Win7/Win8 systems.
    These wireless USB devices have many issues with Win7(and I suspect with Win8) - using Vista drivers with them is almost sure to cause a BSOD.
    Should you want to keep using these devices, be sure to have Win7/Win8 drivers - DO NOT use Vista drivers!!!
    An installable wireless PCI/PCIe card that's plugged into your motherboard is much more robust, reliable, and powerful.
    We use a program that will sort through the drivers, remove the Windows drivers, and will highlight known problem drivers. So that's why I ask you to:

    Please provide this information so we can provide a complete analysis: Blue Screen of Death (BSOD) Posting Instructions

    I manually looked through the driver listing and found these potential problems:

    sptd.sys
    a04pwd2m.SYS
    These drivers belong to Daemon Tools/Alcohol % software
    Daemon Tools (and Alcohol % software) are known to cause BSOD's on some Windows systems (mostly due to the sptd.sys driver, although I have seen dtsoftbus01.sys blamed on several occasions).
    Please un-install the program, then use the following free tool to ensure that the troublesome sptd.sys driver is removed from your system (pick the 32 or 64 bit system depending on your system's configuration): [S] DuplexSecure - FAQ [/S] Link broken as of 21 Jul 2012

    Manual procedure here: Registry and SPTD problems | DAEMON Pro Help
    A number of Creative Audio drivers dating from 2011 (there may be BSOD issues with these drivers in Win8)
    AFAIK there aren't any updates for this - so the software should be uninstalled and the device removed from the system in order to test it.

    athurx.sys wireless driver that dates from 2010 - should be updated to the latest, Win8 compatible version

    cheers thanks for the info gives me plenty to go at

    I'm pretty sure the creative drivers are up to date it was one of the first x-fi models so its getting on a bit now. i do use a tplink wireless receiver for internet to my computer so could quite easily be that. since I've only used it since i installed windows 8. I'm going to post the other dump files because I've wrote on a piece of paper the error and I've got another system file on it so it could be that as well. something called ntoskrnl.exe. so I'll see if i can find that dump again.

    thanks again.

    Right I've updated my tplink driver to the latest one, and updated my creative driver so I'll give it a bit now and see if anything changes I'll post back in a week or so.

    thanks again. i've installed SF_Diagnostic_Tool and on the driver list there's a few going back to 2006 which i gather will be latest drivers but I'll check them out as well.

    Crashed the second day so much for a quick fix

    Right I've uninstalled alcohol 120%, sptd.sys also disabled "kernal debug adapter" in network see if that makes a difference.

    I was thinking if i pulled out my wireless adapter before u shutdown the computer every time, would it still produce this problem? might be a good way of ruling it out.

    Also attached the other files you were after.

    There are reports missing from the upload. Please:

    1) Zip up the contents of the C:\Windows\Minidump directory and upload them with your next post. If there's nothing in there, please follow the instructions here: Set MiniDump

    2) Please generate, zip up, and upload this report:
    MSINFO32:
    Please go to Start and type in "msinfo32.exe" (without the quotes) and press Enter (you can also press Win and R at the same time to open the Run dialog - then type in msinfo32.exe and press Enter)
    Save the report as an .nfo file, then zip up the .nfo file and upload/attach the .zip file with your next post.
    Also, save a copy as a .txt file and include it also (it's much more difficult to read, but we have greater success in getting the info from it).

    If you're having difficulties with the format, please open an elevated (Run as administrator) Command Prompt and type "msinfo32 /nfo C:\Users\Public\Desktop\TEST.NFO" (without the quotes) and press Enter. Then navigate to the C:\Users\Public\Desktop directory to retrieve the TEST.NFO file. If you have difficulties with making this work, please post back.

    You have a Qualcomm Atheros AR7015 Wireless USB Network Adapter:
    I do not recommend using wireless USB network devices. Especially in Win7/Win8 systems.
    These wireless USB devices have many issues with Win7(and I suspect with Win8) - using Vista drivers with them is almost sure to cause a BSOD.
    Should you want to keep using these devices, be sure to have Win7/Win8 drivers - DO NOT use Vista drivers!!!
    An installable wireless PCI/PCIe card that's plugged into your motherboard is much more robust, reliable, and powerful.
    The WER section of MSINFO32 shows BSOD's involving the wifi in February and March. Prior to that there were some video issues that haven't popped back up.

    Alcohol 120% (and Daemon Tools software) are known to cause BSOD's on some Windows systems (mostly due to the sptd.sys driver, although I have seen dtsoftbus01.sys blamed on several occasions).

    Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :

    I've tried uninstalling my creative card and reinstalling and every time I update it to the latest driver which is a 2013 one. I go back in device manager and it still reads as driver version : 6.0.1.1375 22/08/2011 and on there website it says driver version 2.18.0015 date : 25 Jan 13??? am I missing something or is there naming system just screwed up. It says 2.18.0015 on the file. i might try installing the beta one from last year see if it reads properly
