Webcam Software Causes BSOD Indicating Stream.sys

» My Windows 7 64-bit machine has lately become unable to stream any video. Whenever an application tries to pull video from a webcam or stream my desktop as a pseudo-webcam feed, I immediately crash to a blue screen of death. The error CODE is 0x000000C4, and it indicates the file stream.sys. This crash happens instantly with every webcam app I've got, including Skype, WebcamMax, ManyCam, and Google+ Hangouts. It also happens with different cameras, or even when no cam is attached at all.

» When a BSOD (Blue Screen of Death) system failure occurs for most users there is insufficient time to note down in full what it says; the exact text is important to anyone trying to diagnose what is wrong. You can gain the time needed when the error next occurs by following the procedure described below.

If you haven't done so already disable automatic restart on system failure. This should help by allowing time to write down the Stop Error code and related information properly. Select Start, right click on Computer select Properties, Advanced System Settings, Start-Up and Recovery, System Failure and uncheck the box before Automatically Restart. Do not re-enable automatic restart on system failure after getting this information as this setting is best left to not to allow Automatic Restart.

If the system failure occurs during the booting of the computer you need to try a different approach. You can access the Windows Advanced Options Menu on many computers by constantly pressing the F8 (Function) key during Start-Up and selecting the option - Disable automatic restart on system failure. This method is not always easy to use as it can be difficult to depress the F8 at exactly the right time. Try again if it does not work first time. On some computers a different key has to be used.

For a BSOD which not easy to get rid of, just use DLL Suite to fix it. It allows free download of any corrupt or missing dll file, including .sys files and .exe files.

    If the above step fails then I would suggest that you temporary disable the security software installed on the computer and check if it helps.

    Antivirus software can help protect your computer against viruses(Exploit:Win32/CVE-2012-0158.CJ) and other security threats. In most cases, you should not disable your antivirus software. You should re-enable it as soon as you're done.

    I've looked through the log SFC generated, and some of the stuff I'm seeing in there--like "Mismatch between identity keyform and parent key name"--and a little research on it leads me to think I might have some damaged files in my WinSXS folder. This fits with my primary problem, too, since there's a copy of stream.sys under WinSXS.

    If so, the Driver Verifier may be enabled so try disabling the Driver Verifier and see if it helps any: Start > type verifier in the "Search programs and files" box and press "Enter" > Delete existing settings > Finish
