Windows 10 blue screen (BSOD) when starting the camera / webcam, SPUVCbv64.sys

With the recent Windows 10 feature updates to version 1909 and version 2004, some webcam models have started causing blue screens (BSOD) in Windows 10.

We have observed this happening especially for webcams using drivers from a company called Sunsoft IT or something similar.

Fortunately, there is a solution available.

  • Open the Device Manager and right click the webcam -> Properties
  • Click Update Driver
  • Browse my computer for drivers
  • Let me pick from a list of available drivers on my computer
  • On the final screen, choose Microsoft USB device

This will replace the faulty driver with a Microsoft equivalent and hopefully your computer will no longer crash when starting the webcam.

The easiest way to verify that the problem is gone is to start the built in Windows 10 app “Camera” by searching for “Camera” in the Start menu

    • I really hoped this would work. On my HP laptop (ProBook 4540s), there is no final screen that shows Microsoft USB device. Step 4 led me to a screen where I could choose the device I wanted to update, with a choice of “Have Disk” (which I don’t want to mess around with, and anyway I don’t have a Win10 disk) and then it said it updated the driver. It also told me to restart my computer. But after I restarted and tried out the camera, it still gave me the BSOD, same thing.

      Thanks a lot! I was having problems to join a Zoom meeting because the PC kept crashing everytime I turned the camera on.

      This just solved the issue.

  1. Many, many thanks!! Wish I had just looked up your information instead of spending a few worthless hours on the phone with Microsoft. This was easy and helpful!

  2. Problem finally solved when I sought help from Microsoft virtual agent on windows 10, who installed Microsoft driver for me. Thanks to Microsoft!

      If the camera doesn’t show up there, look for something named “Unknown device” further down in the Device mgr. It could also be that your camera is disabled in the laptops BIOS

    Thanks for this in-depth review. I was looking for information about this but didn’t get any information what exactly
    I am looking for. Fortunately, I come across to your website and it helps to make my decision.
    It’s really made my day.
    Thank you again for this great article.

  4. Brilliant! Have this Lenovo Ideapad with built in webcam. BSOD all the time. Did all the recommended driver updates, Windows updates… useless. This neat trick was all it took. Unbelievable messy business!

    This worked very well for some time, but now I have a persistent issue with this. Whenever I enter a video call meeting (usually Zoom_, my camera continuously turns off and when I turn it back on it turns off by itself in about 5 seconds. I have had this issue for a few weeks now. Please let me know if there is any fix. I tried updating the drivers to my old version, and it immediately caused a BSOD.

    Any help would be appreciated.

  7. This helped me a lot. I have 2 different logitech webcams for my stream and out of the blue I got BSOD’s. One of the cams needed an update and it’s all fixed now 😀

  8. Thank you. It finally stopped crashing! Only thing I noticed was that the video quality seems to be much lower, but at least it works now.

    You really make it seem so easy with your presentation but I find this matter to be actually something that I think I would never understand. It seems too complex and extremely broad for me. I am looking forward for your next post, I will try to get the hang of it!

    Was online with Microsoft chat help yesterday because I got the rewrite couldn’t write whatever screen. Couldn’t figure it out. The tech mentioned outside drivers. I still didn’t get it and ask him to specify. The instant he said camera I realized I’d just opened the camera app before I got the BSOD. I replaced the driver yesterday and just check and all it says is USB driver. I’m pretty sure I’ve fixed it.

    Thank you so much, I was just about to give up and buy a new laptop. This was such an easy fix after getting the advice to problems solve. Thank you again.

    Happy Camper

  12. It works! It works!

    Many many thanks. You don’t know how much I am relieved For many years of asking people and searching online I never got the right one until I found this RunTime Asia topic.

    Thank you! Thank you!

    God Bless You More!!!
