How can i use my acer webcam 4736Z

Assuming that your PC is working but webcam is not detected. Just check in device manager whether there is any device showing yellow question mark(which could be your webcam). If it is builtin webcam, then go to Acer website, download and install the appropriate webcam driver for your PC model and OS.

Adjust the settings with the webcam, maybe it needs calibrating. Most webcam has face detection so it needs to be adjusted.

It could be a driver issue, if you have already download the correct driver for it, and still nothing and you get nothing when attempting to use the webcam, then your webcam probraly history. You can check to see if your computer can detect the device in the device manage in your control panel to see if windows detect an imaging device, or any unkown device. If it detect your imagining device such as the webcam, check to see if the driver is installed and is working properly, if nothing is shown in your imagin device, then your webcam is history.

Webcam not detected..

This link is to the Acer USA Driver download website.
They apparently use a couple different cams so check you hardware profile in device manager and see if it says what you have.
Go to this link and get the webcam driver and reinstall it.
