Video Chat Applications (Non-Logitech)

[Ambient13]

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.

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.

Hi Ambient,

The issue you experienced would normally be alleviated by reinstalling the software or upgrading to a newer version. The camera you are using however cannot use any higher software than you currently are LWS 1.1 Am I correct in assuming that everything has worked fine since then? If this is the case it may have simply been an anomaly or small conflict that caused the problem.

Regards,
