Emachines G725 intergrated webcam software?

My emachines G725 comes with a built in webcam for which I have searched all over my computer and internet without any success.

I have seen http://www.nxtguide.com/acer-emachines-e725-windows-7-drivers/ but this will not work at all = Chicony driver is not compatible at all while Suyin is, but causes hard drive(cpu and ram) to skyrocket(video is as a result erratic/freezes and I just can't use this as an option since it would burn hard drive). Where is original webcam driver for g725(g725 uses windows 7 and not xp or vista...) !!? Thank you
