Cameras guides
Webcams, action cameras and memory cards — cameras not detected, power failures and cards a device won’t read.
3 guides
Webcam not working
Fix a webcam that won’t show a picture: the Windows Camera app bypasses every other app and splits the fault in two. Covers the privacy shutter, the three separate permission switches, apps holding the camera, and Device Manager.
GoPro won’t turn on
Fix a GoPro that won’t power on: GoPro’s own sequence starts by removing the SD card, because a corrupted card can hang the camera during boot. Then running it with no battery on external power separates a dead battery from a dead camera.
SD card not detected
Fix a memory card a camera won’t read: a computer and a card reader separate a physical failure from a formatting or compatibility one. Covers the lock switch that slides on its own, where to format, and cards that are merely too slow.
