I have AO722-C5Cbb, everything's fine until a few malfunction programs that forced me to reinstall OS and drivers by the help of the shop where I purchased this notebook. I knew nothing about technology at the time, but recently I figured out that my webcam shows upside down, no matter what program I used for webcam. Registry & startup cleanup is useless. They told me that it may something to do with camera driver. Figured that PC has camera driver, the vendor is LiteOn. But neither Acer Support nor other resources have the cam driver for my PC. What should i do?
