Connect the webcam to your computer. You can skip this step if your computer comes with a pre-installed camera. If you don't have a pre-installed camera, you will need to install the webcam on your computer. Follow all of the manufacturers' instructions closely. Test the camera to be sure that it is working properly.

Choose an instant messaging program to use to chat. A few options include Windows Live Messenger and Skype. Sign up for a free account with your preferred service. Be sure that the party you plan to chat with has her webcam and account set up as well.

Launch the instant messaging program. Before you can call the other person, you need to open the program on your computer. If you are prompted to sign in, enter the username and password you chose when you signed up for the account.

Add your chat buddy to your contact list. Before you can start chatting through your webcam, you need to make sure that the other person is on your list of contacts. In Windows Live Messenger, click "Add a Contact". Follow the instructions. In Skype, select "Contact", then "New Contact". Follow the instructions to find your friend or family member and request her as a contact.

Call your friend or relative. If you use Skype, highlight the name of the contact you want to reach for chat. Click the "Call" option at the top of the screen. Select "Video Call". In Windows Live Messenger, click "Actions", "Video", "Start a video chat". Once the other person answers the call, you can chat as long as you want.
