Hi,
Please do try these troubleshooting steps that may help in solving the issue.
- Start by going into Control Panel then go to Imaging Devices and check if your webcam is listed or not.
- If it's listed normally, try opening the webcam software (Crystal Eye) and check if it will work or not.
- If your webcam is not listed that means it's a hardware problem, you may need to open the laptop and check if the webcam ribbon cable is connected properly in the motherboard.
- Another troubleshooting you can do if the webcam is listed but not working is to run a Factory reset to reinstall windows itself.
