camera not working

Question

My camera is not working even after all the troubleshooting steps on my hp EliteOne 800

Answer 1

Hi Zee,

I understand how frustrating it can be when the built‑in camera still doesn’t work even after you’ve tried multiple troubleshooting steps. Have you already tried the Q&A Assist suggestions? In addition, please try the following.

Step 1: Confirm Windows camera privacy settings

Even if drivers are present, Windows can block the camera at the OS level.

1. Go to Start > Settings
2. Open “Privacy & security” > “Camera”
3. Make sure the following are On:
   • “Camera access”
   • “Let apps access your camera”
   • “Let desktop apps access your camera”

Step 2: Check whether the camera is disabled in Camera settings

Windows 11 can disable cameras at the device level.

1. Go to Settings > “Bluetooth & devices” > “Cameras”
2. Look under “Disabled cameras”
3. If your HP camera appears there, select it and click “Enable”
4. Restart the PC and test again with the Camera app

Answer 3

On an HP EliteOne 800 where the camera still fails after basic checks, focus on confirming that Windows can see the device, that the driver is correct, and that the hardware is compatible.

Use this sequence:

1. Test in the Windows Camera app
   1. Open Start > Camera.
   2. If the preview works here but not in other apps, the problem is with those apps’ settings.
   3. If the Camera app shows a black screen or an error, continue with the next steps.
2. Install Windows updates and restart
   1. Go to Start > Settings > Update & Security > Windows Update > Check for updates.
   2. If View optional updates appears, open it and install any camera‑related or driver updates.
   3. Restart the PC (a full restart, not just waking from sleep) and test the Camera app again.
3. Verify the camera in Device Manager
   1. In the taskbar search box, type device manager and open it.
   2. Look for the camera under Cameras, Imaging devices, or Sound, video and game controllers.
   3. If the camera is missing:
      • On the Action menu, select Scan for hardware changes.
      • Wait for detection to complete, restart the PC, and test the Camera app.
4. Check for an incompatible (very old) driver
   1. In Device Manager, right‑click the camera entry and choose Properties.
   2. Open the Driver tab and select Driver Details.
   3. If any listed file name includes stream.sys, the camera was designed before Windows 7 and is not supported on current Windows versions; replacement hardware is required.
5. Roll back the driver if the issue started after an update
   1. In Device Manager, right‑click the camera > Properties.
   2. On the Driver tab, select Roll Back Driver (if available), then confirm with Yes.
   3. Restart the device and test the Camera app.
6. Completely reinstall the camera driver
   1. In Device Manager, right‑click the camera and select Properties.
   2. Go to the Driver tab and choose Uninstall Device.
   3. Enable Delete the driver software for this device, then select OK.
   4. In Device Manager, open the Action menu and select Scan for hardware changes.
   5. After Windows reinstalls the driver, restart and test the Camera app again.
7. Try the in‑box UVC driver instead of the OEM driver Many USB webcams (and integrated modules) support the standard USB Video Class (UVC) driver built into Windows. Switching to it can resolve driver issues, though some advanced features (for example, Windows Hello face recognition) may stop working.
   1. In Device Manager, locate the problematic webcam under Cameras or Imaging devices.
   2. Right‑click it and select Update driver.
   3. Choose Browse my computer for drivers.
   4. Select Let me pick from a list of available drivers on my computer.
   5. Pick USB Video Device, then select Next to apply it.
   6. Select Close, confirm the camera now appears under Cameras, and test in the Camera app.
8. If all software steps fail After these steps, remaining likely causes are:
   • A hardware fault in the integrated camera module on the HP EliteOne 800.
   • A vendor‑specific driver or firmware issue that requires updated HP drivers or direct HP support.

In that situation, install the latest camera/webcam driver package from HP’s support page for the exact EliteOne 800 model. If the camera still does not work in the Windows Camera app after that, treat it as a hardware issue and contact HP for diagnostics or repair.
