Webcam and Microphone Failure Due to Driver Instability

This cause is suspected if the hardware is detected but fails to initialize or displays static/black screens. Confirm by verifying the driver status in Device Manager; if the device displays a yellow exclamation mark or an 'Error Code 10' or 'Error Code 43', the driver stack is corrupted or incompatible with the current Windows build. Testing the camera in the HP PC Hardware Diagnostics UEFI environment is required; if the device works in the BIOS environment but fails in Windows, it confirms a software-level driver conflict.
