Bugcheck 0x0000009f reboot


  • I keep getting bugcheck 0x9f. The pc reboots after a blue screen however it never happens when I am using the pc. Some times when the pc is in standby or other times when it is recording tv etc.

    The computer has rebooted from a bugcheck. The bugcheck was: 0x0000009f (0x0000000000000003, 0xfffffa8005234060, 0xfffff80000b9c518, 0xfffffa80067828e0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 052011-27471-01.

    I have been getting these crashes at least once every 2-3 days. I have tried doing s harddrive scan disk and a memory check. I have also tried updating my graphics drivers to the latest but with no effect.  The mini dmp files from the last month can be found...

  • Hi,

    Results verified by WinDBG, DumpCHK, and BlueScreenView.

    The Bug_Checks were all 9F CAUSE hcw95bda.sys which is the Hauppauge driver.

    BugCheck 9F, {3, fffffa8005234060, fffff80000b9c518, fffffa80067828e0}
    FAILURE_BUCKET_ID:  X64_0x9F_3_hcw95bda_IMAGE_usbhub.sys
    BUCKET_ID:  X64_0x9F_3_hcw95bda_IMAGE_usbhub.sys

    1. Update the Hauppauge driver.

    2. Check with GigaByte for updated BIOS, low level chipset drivers, USB drivers and other on-board

    BiosVersion = F11
    BiosReleaseDate = 04/22/2010
    SystemManufacturer = Gigabyte Technology Co., Ltd.
    SystemProductName = EP45-UD3LR

    Other methods to troubleshoot if needed :

    Are you using any Roxio or Nero programs? These have been known to cause this problem even
    if they were working well for a long period of time. If so check with their support.


    Check these :

    Error message when you try to resume a Windows 7-based or a Windows Server 2008 R2-based
    computer from hibernation: "Stop 0x0000009F"

    Stop error when you put a computer that is running Windows 7 or Windows Server 2008 R2 to
    sleep or into hibernation, or when you restart the computer: "0x9F"

    "0x0000009F" Stop error message when a computer enters and resumes from hibernation in
    Windows 7 or Windows Server 2008 R2

    This one is possible if BlueScreenView OR MyEventViewer (or EventViewer) shows the appropriate code.

    Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: “The system has
    rebooted without cleanly shutting down first”

    And :

    "Stop 0x9F" or "Stop 0xFE" error on a Windows 7-based or Windows Vista-based computer that
    uses certain AMD USB EHCI host controllers

    KB Search 0x0000009F with the above and a few other articles (check this as there may be new articles
    added to the KB)

    Check this thread for information using BlueScreenView, MyEventViewer and other methods
    to troubleshoot BlueScreens - top 3 replies.

    We can analyze the minidumps if you make them available from the SkyDrive or other file
    sharing sites.

    Zip or upload the contents of C:\Windows\minidump

    Use SkyDrive to upload collected files.


    Check with these utilities to see if any information can be gathered : (Be sure to run this since there
    may well be other Bug_Check codes.)

    This is an excellent tool for posting Blue Screen Error Information

    BlueScreenView - Free - scans all your minidump files created during 'blue screen of death' crashes,
    and displays the information about all crashes in one table.


    MyEventViewer can be checked at the time of the BlueScreen (BSOD) to within a second or so of the
    time of the BSOD to provide more information as to possible cause - see TIP.

    MyEventViewer - Free - a simple alternative to the standard event viewer of Windows.
    TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file -
    set it to a bit before and after the time of the BSOD.


    AppCrashView - Free - a small utility for Windows Vista and Windows 7 that displays the details of all
    application crashes occurred in your system. The crashes information is extracted from the .wer
    files created by the Windows Error Reporting (WER) component of the operating system every
    time that a crash is occurred. AppCrashView also allows you to easily save the crashes list to
    text/csv/html/xml file.


    References to Vista also apply to Windows 7.

    This "could" be a power supply problem though it is not the most common cause.

    9f is likely a driver issue. Antivirus/antispware/security programs can also cause these issues.
    Have you added devices lately or updated drivers - be sure to check in Windows Updates to see
    if a driver was updated prior to this occurring. This could also be caused by a loose card or cable
    and even a weak power supply.

    That error means a driver is not handling the power state properly. Check in Control Panel - Device
    Manager to be sure major drivers are not shut off during sleep - double click Display Adapter - NIC
    and WIFI - Sound and others - Power Management tab - uncheck Allow computer to turn off power.
    Maybe only one has an issue.

    Start - type in Search box - MSCONFIG  find at top - Right Click - RUN AS ADMIN

    General Tab - check Diagnostic Start  - APPLY / OK  -  REBOOT

    Try it now. If it still blue screens think Video Driver. If not think NIC, Wifi, Sound, or......
    (and it still could be video interacting with something else). See troubleshooter link
    above for my generic driver update methods.

    BCCode: 9F  0x0000009F  <-- read this link*1167.html?order=date

    See the troubleshooter links posted above for methods to update drivers.

    Hope this helps.
