Skype BSOD crash during video call, caused by webcam drivers; Vista SP2 RRS feed

  • Question

  • Description: BSOD occurred during video conference on non-logitech application (Skype). I initially thought that it might've had something to do with the Graphics driver update I applied this morning.

    However, based on the dump file, the error was evidently caused by the webcam drivers - for some reason the webcam stopped working DURING the conversation, thus the crash. I had to restart the PC and reconnect the USB for the webcam to work again; the next conversation went well but I would still like to troubleshoot this problem so as to avoid it in the future.

    PS: I posted this on the logitech webcam forum too.

    BlueScreenView renders the BSOD error screen as follows:

    A problem has been detected and Windows has been shut down to prevent damage to your computer.

    The problem seems to be caused by the following file: lvrs.sys

    SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

    If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

    Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

    If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

    Please help me resolve this issue. Hopefully Logitech can come up with some sort of fix; but at the very least, I would be grateful to have some input on what the best course of action is. Thanks.

  • The Stop 0x7E (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) is a very common bug check: it indicates that a system thread generated an exception that the error handler did not catch.
    The value of parameter 1 (0xC0000005, STATUS_ACCESS_VIOLATION) indicates a memory access violation occurred.

    As you can see from the debugging informations, the problem is related to the driver of your webcam: the possible solutions are disabling the driver or checking with the manufacturer for driver updates.

    Bye.
