I have a MSI A5000 laptop. All the specs on it say it has a built in webcam. But it doesn't show up on my pc and there is no software. The camera lens is there and it has a on/off button but nothing happens. System info doesn't list it either and MSI offers no support or drivers. It just says n/a. How do I find out if it is actually installed. I have seen on Google that people actually have one on their unit but that it works for awhile and then stops. Any suggestions or Ideas?
