Your camera stops working because of a driver issue, permission block, hardware conflict, or a physical obstruction—and most of these you can fix yourself in minutes
A camera that was working yesterday and stopped today usually points to one of four problems: the software that runs your camera (the driver) has crashed or needs an update, your operating system is blocking camera access, another program is using the camera, or the camera hardware itself has failed. Start by checking whether the camera works in a different program—if it does, the problem is software permissions, not hardware. If it doesn't work anywhere, move to driver updates and hardware checks.
Before you do anything else, look at your camera lens. Dust, a sticker, or a sliding cover can completely block the view. Wipe the lens gently with a soft, dry cloth. If your laptop has a physical camera shutter, make sure it is open. These straightforward checks solve the problem in roughly one out of every five cases.
Key Takeaways
- Check whether your camera works in a different program first—if it does, the problem is a permission or software conflict, not hardware failure.
- Windows and Mac both have operating system settings that can block camera access; you may need to turn on permission for the program you want to use.
- If another program is already using your camera, close it completely before opening a new one—most cameras cannot be accessed by two programs at the same time.
- Updating your camera driver (the software that runs the hardware) fixes most camera problems that are not caused by permissions or physical damage.
- If your camera still does not work after checking permissions and updating drivers, the hardware itself may have failed and you may need to replace it.
Check camera permissions in Windows 10 and 11
Windows blocks camera access by default for most programs unless you explicitly turn it on. Open Settings, then go to Privacy & security on the left side. Click Camera. You will see a toggle at the top that says Camera access—make sure it is turned on (the toggle should be blue). Below that, you will see a list of individual programs. Find the program you want to use your camera with and make sure its toggle is also on.
If the program you want is not listed, it may not have asked for permission yet. Open that program, try to use the camera, and Windows will prompt you to allow access. Click Yes. Then go back to Settings and verify the toggle is on.
After you turn on permissions, close the program completely and open it again. Permission changes sometimes do not take effect until the program restarts.
Check camera permissions on Mac
Mac handles camera permissions differently than Windows. Open System Settings, then click Privacy & Security on the left. Scroll down and click Camera. You will see a list of programs that have requested camera access. If the program you want to use is not listed, it has not asked for permission yet.
Open the program and try to use the camera. Mac will show a prompt asking whether to allow access. Click Allow. If you accidentally clicked Don't Allow before, you can come back to this same Privacy & Security screen and remove the program from the list, then try again—the prompt will appear once more.
Close the program completely after changing permissions, then open it again.
Update your camera driver on Windows
The software that runs your camera hardware is called a driver. When a driver becomes outdated or corrupted, the camera stops working even though the hardware is fine. Open the Device Manager by right-clicking the Windows Start button and selecting it from the menu. Look for Cameras in the list and click the arrow next to it to expand it.
Right-click your camera name and select Update driver. Windows will offer two options: Search automatically for updated driver software and Browse my computer for driver software. Choose the automatic option first. Windows will search online and install any newer version it finds. Restart your computer when it finishes.
If automatic update finds nothing, try the manual option. You will need to visit your camera manufacturer's website (look for the brand name on your camera or in Device Manager), read the latest driver for your specific camera model, and follow their installation instructions. Common camera manufacturers include Logitech, Razer, and Microsoft, but built-in laptop cameras vary by manufacturer.
Update your camera driver on Mac
Mac does not use drivers the same way Windows does—the operating system usually handles camera hardware directly. However, if you are using an external camera (like a Logitech or Razer model), the manufacturer may provide software updates. Visit the manufacturer's website, find your camera model, and read any available software or firmware updates. Follow their installation instructions and restart your Mac.
If you are using your Mac's built-in camera and it stopped working, the problem is usually permissions (covered above) or a hardware failure. Restart your Mac first—this solves many temporary issues. If the camera still does not work after restarting and permissions are turned on, the hardware may have failed.
Close other programs that might be using your camera
Only one program can use your camera at a time on most computers. If another program is already using it, a new program will not be able to access it. Check your taskbar (Windows) or Dock (Mac) for any video or communication programs that might be running in the background. Common culprits are Zoom, Skype, Discord, OBS, and Google Meet. Close these programs completely—minimizing them is not enough.
On Windows, you can also open Task Manager by pressing Ctrl+Shift+Esc, look through the list of running programs, and close anything that might be using the camera. On Mac, open Activity Monitor from Applications > Utilities, find the program, and click the X button to close it.
After closing other programs, open the program you want to use and try the camera again.
Test your camera in a built-in program
If your camera does not work in Zoom or another third-party program, test it in a program that comes with your operating system. On Windows 10 and 11, open the Camera app (search for it in the Start menu). On Mac, open Photo Booth (in Applications > Utilities). If the camera works in these built-in programs, the problem is not hardware—it is a permission or software conflict with the third-party program you were trying to use.
If the camera does not work in the built-in program either, the problem is likely a driver issue (covered above) or hardware failure. If you have already updated drivers and checked permissions, and the camera still does not work anywhere, the hardware may have failed and you may need to replace it or contact the manufacturer for support.
Frequently Asked Questions
Why does my camera work in one program but not another?
The program that is not working probably does not have camera permission turned on. Go to your operating system's privacy settings (Settings > Privacy & Security > Camera on Windows, or System Settings > Privacy & Security > Camera on Mac) and make sure the program is listed and its toggle is on. Close the program completely and open it again.
My camera light is on but the picture is black or frozen
A black picture usually means the lens is blocked by dust, a sticker, or a sliding cover. Wipe the lens gently with a soft cloth. If the picture is frozen, close the program completely and open it again. If it stays frozen, restart your computer. If restarting does not help, try updating your camera driver.
Can I use my phone as a webcam instead?
Yes. Apps like Droidcam (Android) and EpocCam (iPhone) let you use your phone's camera as a computer webcam over Wi-Fi or USB. read the app on your phone and the companion software on your computer, then follow the app's setup instructions. This works as a temporary solution while you fix your computer camera.
What should I do if updating the driver does not fix it?
Restart your computer, then check permissions again to make sure they are still on. If the camera still does not work in any program, the hardware may have failed. Contact your camera manufacturer's support team with your camera model number, or if it is a built-in laptop camera, contact your laptop manufacturer.
Is my camera broken if it worked yesterday but not today?
Not necessarily. Hardware usually fails gradually, not suddenly. A sudden stop usually points to a driver crash, a permission change, or another program blocking access. Start with the permission and driver checks above. If those do not work, restart your computer. Hardware failure is the least likely cause of a sudden stop.
