BSOD immediately after booting, System_Thread_Exception_Not_Handled

**ksuthayya** · 04 Apr 2017

Hi,

So this is the 4th time my PC has crashed because of the same file in the past 2 years. The file that is constantly causing the BSOD is rtsuvc.sys which is the Lenovo EasyCamera driver, ie Webcam driver.

Error: System_Thread_Exception_Not_Handled
File: rtsuvc.sys

To bring you up to speed wrt my issue, please refer to System_Thread_Exception_Not_Handled - Microsoft Community AND https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/lenovo-y510p-unsupported-for-win-10-camera-driver/bf186d1c-6bb1-4723-a19b-5951c830d771

All of this has been cause as Lenovo decided not to support my PC for W10 and as a result there is no compatible webcam driver for my PC and W10.

So it's been a while since my last crash and since then I've come to realise that there's not much that I can do to find/get a driver that would enable me to use my webcam and hence I have accepted the fact that the in-built webcam is dead.

Immediately after the BSOD when I booted I went to my Device Manager and uninstalled "Lenovo Easy Camera" driver from my Imaging Devices tab. This isn't the first time I've uninstalled it, it keeps coming back. I've finally bought a USB webcam and want to PERMANENTLY disable my in-built webcam and all drivers/software pertaining to it.

Please help with the same.

I've attached the DMP Log file. Attachment 128153 Attachment 128153

It might be a case of needing to physically disconnect the built-in webcam to prevent it being recognised as a connected device. Lenovo usually provides hardware manuals for replacing components so you might be able to do this yourself.

Edit: Just had another idea - it would be simpler to disable the camera in the BIOS. If you Enter the BIOS settings go to the security tab and select the I/O Port Access options; set the Integrated Camera Interface to LOCKED. This should permanently disable the camera.

@philc43

Thanks, I was looking for just that kind of a fix. Something that ensure the PC will never scan for "hardware changes" and detect the cam and then re-install the drivers/softwares associated with the camera.

I just want to be sure of what I'm doing when I do it though. I shouldn't disable to possibility of a webcam and as a result disable any USB webcam that I plug in. Could you give me the exact steps for the same, ensuring that this is only for the built-in webcam and it's drivers/softwares

The BIOS fix will only apply to the port setting used for the built in camera. Attaching another USB camera will not be affected by this bios setting.

I do not know for sure what your BIOS settings are but these are the steps required on a Lenovo ThinkPad Laptop that I have.

When starting the laptop hit the F1 key which allows you to enter the BIOS (it might be some other key for your ideaPad)
Use the right arrow key to navigate to the Security Page
Use the down arrow key to navigate to the I/O Port Access and press enter to access the settings
Use the Down arrow key to move to the Intergrated Camera Interface
Use the Enter key to access and change from UNLOCKED to LOCKED
Save changes and exit

Hope this helps :)

Hi,

As you can see in the image, there is no option for I/O Port Access under Security. There wasn't one in Configuration either.

Great, seems like disabling the BIOS for the camera is almost the same as manually unplugging the camera as the computer blocks out the hardware port that the camera is connected to, correct? Is there any way for the PC to manually turn it back on?
Once this is done, I can safely remove all the built-in camera related drivers without caring about them, correct?

**philc43** · 04 Apr 2017

The IdeaPad must use a different BIOS, sorry that my idea did not work out. As you say, disabling it the BIOS would have had the same effect as unplugging it but it looks like you will have to resort to the hard way of physically disconnecting it inside the laptop.

Ahh, nevermind. Thanks for your help and time on this.

Can you disable it in Device Manager?

Hi

Just crashed again this morning. Same file, same error.

DMP - Microsoft OneDrive - Access files anywhere. Create docs with free Office Online. (It's not a 0KB file size like last time so hopefully it shouldn't be corrupted).

Also, somehow .. "Lenovo Easy Camera" is showing up in my Device Managaer even though I'd uninstalled and disabled it previously, a week ago. (Image attached)

Please help with this, I only want to continue using W10 and this PC without trying to use the inbuilt webcam or anything related.
