Windows 7 RC Crashes (100% load, sound stutters, USB the cause?) RRS feed

  • Question

  • This issue has popped up a few times since my install of Windows 7 (64 bit).

    I first noticed it when I was watching tv using Windows Media Center.  A few minutes of watching tv, the entire OS would crash.  The sound would stutter, the screen would slow, the mouse would respond, but eventually the machine would just freeze.  I attempted to replicate the issue, with success, although I took a bit longer of watching tv.

    In the task manager, the CPU load would be under full 100% load, but no processes would show even close to the load, or added to full load.  I attributed it to my TV tuner (Happauge 980, USB stick), and stopped watching tv.

    Today, I was attempting to drag some video files off my PSP (using the USB) when again, the same problem arose.  100% load, no processes adding to full load.

    The event viewer is completely useless in finding out any information that could have caused the crash.  Nothing at all that hints to what the problem is.

    Could it be faulty USB drivers?  I have not installed any drivers for the USB other than the initial drivers Windows 7 installed.  I understand this is a RC, and not the final version, but this is getting kind tiresome.  Only crashes under load on usb....

    Any help would be appreicated.

    Thank you

  • I have finally solved the (Dell) Angel USB TV Problem with Windows Media Center crashing, or often lag problems, and random freezing. I have confirmed this fix on the following operating systems:

    Windows XP Media Center
    Windows Vista Home Media Center
    Windows 7 RC Media Center

    using (Dell) Angel Emuzed USB TV tuner.

    PROBLEM: The USB device does not have enough power to survive while powering TV on Windows Media Center.
    SOLVED: To fix the Windows Media Center crash after a minute of TV problem add a USB doubler that will give more electricity to the USB device. (For those who are unfamiliar with these doublers, it is a cable that plugs into two USB ports on the computer but merges into one that the device connects into.

  • Hi buhgey,

    Perhaps it would be useful to try capturing an xperf trace.  For Windows 7, download and install the Windows 7 RC1 SDK which contains xperf 4.5.  Find xperf.exe on your system (may need to look for an MSI for the Windows Performance Toolkit and install that first).  Then, from an elevated CMD prompt change to the folder containing xperf.exe and execute:
     xperf -on DiagEasy+PROFILE

    Then, just after reproducing the problem, run:
     xperf –d merged.etl

    Then, ZIP merged.etl and password protect it.  Upload the ZIP file somewhere, and share the location either publicly or privately.  Share the password privately with those you would have analyze the log.

  • Thanks for the response.  I am downloading that iso as we speak.

    As for password protecting the file, what type of information will the zipped file contain?

    I will get that all ran, and will hopefully find someone who knows what they are looking for.  The only issue, is that the system becomes unstable after hitting load, and will freeze up.  Will the xperf zip file contain the dump when the pc freezes?

  • The sound would stutter, the screen would slow, the mouse would respond, but eventually the machine would just freeze.
    The idea would be to run the xperf -d command before the freeze, but of course after the problems begin.  But kernel.etl (at the root of the drive) may be available and perhaps salvageable, after a hard boot.  Not sure - we'd have to see.


    what type of information will the zipped file contain?
    The file will contain, at a minimum, various details about the system, hardware, processes running, paths to files, etc.
    and will hopefully find someone
    I'd be interested in having a look...

  • Are you by chance running an ASUS motherboard? I was having the same problems and just found a solution today. If you are running an Asus motherboard try going to the ASUS website and downloading PC Probe II. It has updated ACPI drivers that seem to straighten things out. I'm going on the 12th hour of up time with absolutely no problems. I've even transfered an 8GB file off my external USB hdd with no issues. The link to the asus driver update site follows.

    http://support.asus.com/download/Download.aspx?SLanguage=en-us

    Don't install PC Probe II just go in to device manager and manually update the "... ACPI UTILITY" under the system group in device manager. Load the driver from the appropriate folder in the PC Probe II directory.

    I came by the solution after I found the following thread here on technet and noticed I had similar errors in event viewer.

  • I'm having a similar problem with my Asus P7H55-M PRO board with Windows 7 x64 Media Center.  I was originally having much more problems with crashing, but was able to narrow those down to a bad OCZ memory stick by useing memtest86.  Now I have the good memory stick and the most updated Intel HD Graphics drivers for the built in graphics on my i3.  Yet, even after updating the ACPI driver (and every other driver I could find) I'm still having the problem with MCE sound suddenly stuttering and the application crashing.  It does seem that this may happen more often if I leave the TV on overnight with the monitor off (though this may be just because of the length of time the video is left on).

    Anyone have a similar issue and been successful finding a solution?
