Webcam isn't working

[bmcaleer67]

Hi,
All of a sudden, my webcam visual isn't working; it cuts out, colours go all wonky, displays shake.
My drivers are all up to date. My videos from Netflix, etc. all play fine, but when I go to record a personal video, it doesn't work. Help!

PS I am on Windows 8.1 and webcam is internal.
