That is super odd... I never heard of a webcam being used for screenshots.
I would suggest in the search box on task bar, type in "Device Manager" > open device manager (control panel) from the results > find Imaging devices on the list and expand that category. Uninstall all devices marked "webcam."
Reboot. See if it installs new devices. If not, open device manager again > click Action, then scan for new hardware > scroll to Imaging devices and expand. Then search for drivers for the newly found devices if they still don't install.
I have searched around and it is hard for me to find out on HO what actual webcam device they built into that notebook.
