I disassembled my webcam and tried to find out what was wrong with it. With the plastic casing removed, it is basically just a circuit board, a CCD and a lens. I made the mistake of resting the naked camera on top of an aluminum can while it was plugged in. The metal of the can made a short circuit on the circuit board and the computer prompty rebooted. Note to self: don't do that again. The vertical syncrhonization problem persisted after the computer started up again. But the next day, the camera started working fine again; I haven't seen the problem since. I have no idea what caused the problem in the first place, or what fixed it. Oh well -- at least it's working now.
