  • Blue screen after installing the driver for windows phone 7

    Hi all

    I installed the new version of Zune. When I connect my Windows 7 phone (HTC Mozart) to my computer (Vista SP1), the driver will install automatically. After that, he tells me to restart. When I do this, and when windows starts again, theres a BSOD with the following message:
    Driver IRQL not less or equal
    This only happens when I installed the driver for my phone.
    Once windows restarts and gets me to error checking etc and after that, it tries to start Windows again go through the process of "update configuration". Naturally the updates are not properly configured, and it restarts and tries to restore changes. This pretty much goes in a loop forever, until I restart, run in safe mode.
    I have no idea why what is happening, and search on Google did not help so far. Any help would be appreciated.
    Thank you.
    Euler

    The minidump files show the recent errors are errors IRQL_NOT_LESS_OR_EQUAL (a) and the cause of the error is OA001Vid.sys.

    The OA001Ufd.sys also seems to be involved in the accident.

    These two drivers seem to be the drivers for the integrated webcam.

    What you might try is the next update for the webcam to the laptop:

  • If Windows will send a message when she install the driver for a USB device successfully or unsuccessfully?

    As you know, the window search and install the driver for a new device (USB) coming. We can get the status of the device through Device Manager manually. but I was blocked by the following questions when trying to obtain programmatically.

    Is it possible for me to get the driver installation progress window? Or how could I get the event that she has finished the installation and the result (install has failed or succeeded)?

    Best regards

    -Alvin Hu

    Vista does not send these messages and cannot be configured to do this (progress or when it is done or if it succeeded or failed).  The only way to make sure is to plug and then, go to start / Control Panel / Device Manager and check for the device and click on it for more information on its status.  You can also check if the appliance does not work - it's probably faster and more accurate.  Many USB devices indicate their status by starting to work (a mouse begins to scroll, a USB flash drive or an external USB drive to bring the Autorun screen or appear in the Windows Explorer,...) and USB devices tend to start working quickly enough so it should not be a long wait.

    I hope this helps.

    Good luck!

  • do not install the driver for XP photosmart 5510

    I tried in vain several times to install the driver for my refurbished XP for my laptop HP photosmart 5510. I said I want to install via radio - he finds the printer and lets me select - then it starts the installation.  It gets about two-thirds through the bar of "installing network printer." "and crashes.

    I let it rest, go to walk my dogs, prepare dinner, and it moves of there.  When I click on cancel, it crashes during the phase cancellation and I'm relegated to "force quit" process.  It's annoying!  All I want to do is wireless printing.  Scanning the computer would be an asset.

    BTW, I had NOT of PROBLEMS installation on laptop of my wife under System 7.

    Help, please... Thank you

    Hi Sameer,

    Thanks for posting your query on the Microsoft Community.

    According to the description, I understand that you are getting an error code.

    I would like to know some information.

    1. You are connected to a domain network?

    2. When exactly do you get this error code?

    3. Do you also have any error message?

    This problem may occur if the print spooler service is stopped.

    To start the spooler service, follow these steps:

    1. click on Startand then click Control Panel.

    2. double-click Administrative Toolsand then click Services.

    3. double-click on the Printer Spooler service and then change the startup type to Automatic. This option sets the spooler service starts automatically when you restart the computer.

    4. If you want to start the spooler service immediately, click Start in the area of The State of the Service .

    I would also refer to the Microsoft Help Article below and check if that helps.
