My acer aspire 5570Z built in cam is not working

Pravin is Correct If you need Driver for your acer aspire 5570Z Camera you can download it from http://www.downloadya.com/files.php?cat=11

go to
Start - Control Panel - Classic view - Administrative tools - Computer Management - Device Manager
and look to see if it shows up on the right, if you see "unknown devices" regarding ur webcam and it's not showing, guess what...it doesn't recogize it.
So, simply go download the driver for it (find it on google or on motherboard site), then go to device manager, and uninstall the device, or simply restart the computer, and it should auto attempt to install it. :) install the drivers properly and u will find it working.

if not solved then problem with ur camera if u want to download drivers than pls follow the foolowing steps

1. you can get your drivers .
just go to ur webcam manufacturing site, click on download section click on drivers, enter its model number and download the camera drivers .
2. If you don't know the webcam drivers cd then connect to internet, uninstall all the old webcam drivers if any. then when pop up window says that new hard driver is found then click it and it will automatically install drivers from net

3. If you want to know about your webcam drivers, then go to desktop
a. right click on my_computer,

b.then select properties, in properties tab click on the HARDWARE tab,

c.then click on the device manager tab, then select and expand the drivers like sound or video which you want to know.

d. right click on the selected sound or display drivers and select its properties.
