Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem.
What program are you trying to use the webcam in?
If it is a website then yes. But then I would also need to know what web browser you are using. It is the program you use to open the internet.
Can you try something like Skype? If the webcam works in Skype it would mean the website is the problem.
