what is bugcheckcode 307 and how do I fix it?

Question

Today, when I was trying to watch a video, I got a notification from audio troubleshooter and when I checked it out, it stated that there was a problem with the diagnostics, then my laptop completely shut down. I check the crash log, and it says bug check code 307. I haven't noticed anything wrong with the audio and never received an audio troubleshooter notification before. I also check the audio drivers, and they are all up to date with the latest windows update.

Edit: I got the audio troubleshooter notification again, and whne i didn't click on it, I still crashed to a system service exception.

See if your computer is creating minidump files.

To find these files, this is the path "C:\Windows\Minidump".

First copy and paste all the minidump files you have to another folder and then zip it. Then upload the ZIP file to the cloud OneDrive.

Choose to share or right click and get the share link.

Please post the link to the ZIP file here so it can be reviewed.
