Check whether the Webcam is listed in Device manager Go to Start right click on computer click on manage , click on Device manager , In Device manager under imaging devices see whether there is webcam listed , if not install the webcam driver from www.support.acer.com, Check whether the Webcam Application is listed in All programs, if not Re-Install the Software from Acer Recovery manager Access Recovery Manager by going to All Programs ->Acer-> Acer Recovery manager -> Restore-> Restore Drivers and Applications , Select webcam software to Install

If your Notebook is installed with Vista, there is no option to start the Webcam directly without using any application.
However, you can try using the HP Webcam drivers which are for XP with which you will get a Preview window to use the webcam without using any application like Messengers etc..:
Download the above mentioned driver from the link below :
ftp://ftp.hp.com/pub/softpaq/sp35001-35500/sp35414.exe

Save the file in the Notebook and double click once the file is saved to install the drivers.
However, if you are unable to access the webcam using Quickplay application, I recommend you to try reinstalling the application by following the instructions below if the Recovery Partition is available and you are able to use the Recovery Manager application :
Click on Start and then on Control Panel in the window that appears, click on Classic View in the left pane.
Now, among the icons that are displayed, double click on Programs and Features icon and among the list that is displayed, click on HP Quickplay and click on Uninstall button on the top.
Now, follow the instructions available in the link below to reinstall Quickplay using Recovery Manager :

You can also try downloading Cyberlink YouCam application which is provided for all latest Notebooks to access Webcam from the link below :
ftp://ftp.hp.com/pub/softpaq/sp39001-39500/sp39372.exe

Save the file into the Notebook and double click the file to install the application.
