Spectre x360 iacamera64.sys Blue screen of death

[SupremeStaffing]

I have a Spectre x360 that will periodically get a BSOD and when using windbg it points it directly to the iacamera64.sys driver. I have tried all the typical driver troubleshooting: restarting the driver and device, uninstalling and reinstalling the driver, updating it but there is no update, reverting it but there is no previous version to the driver, running the typical diagnostics on the disk, processor, and OS has shown nothing, there are no bios settings having to do with the camera for this device, and the built in driver has no alternatives. Disabling the device is not an option. This issue has been apparent for years and I'd love to finally find a solution.

Hi @SupremeStaffing,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you’re dealing with a persistent issue related to the iacamera64.sys driver, which is responsible for Intel RealSense or integrated camera functions. The fact that typical driver troubleshooting steps haven't resolved the issue suggests this could be related to deeper system incompatibilities or driver conflicts. Below are a few more advanced solutions you can try.

Check for Intel DCH Drivers

Intel sometimes releases Intel DCH (Declarative, Componentized, Hardware Support App) drivers for its camera modules. These may not always be automatically updated through Windows Update or your device manufacturer. You can manually check for the latest camera drivers on Intel’s website:

• Go to Intel's Download Center
• Search for "RealSense Camera" or "Intel Camera Drivers"
• Install the latest DCH drivers if available.

Windows 10/11 Update Compatibility

• Ensure that Windows is fully updated. Major updates could provide necessary patches for system stability, particularly with older drivers.
• If the issue arose after a specific Windows update, consider rolling back to a previous version of Windows (before the update) to test if the BSOD still occurs.

Run System File Checker (SFC) and DISM

Corrupted system files could cause conflicts with drivers, so running these built-in Windows tools might help:

SFC Scan:

1. Open Command Prompt as an administrator.
2. Run: sfc /scannow
3. Reboot your system if any issues are detected and repaired.

DISM (Deployment Image Servicing and Management):

1. In Command Prompt, run the following commands:

dism /online /cleanup-image /scanhealth 

dism /online /cleanup-image /restorehealth

1. Reboot the system after the process completes.

Try Using an Older or Generic Camera Driver

If your current version of the iacamera64.sys driver is causing BSODs and there’s no update available:

• Try manually installing an older version of the driver, even if it’s not listed under previous versions.
• You can try using a generic Windows camera driver:
  1. In Device Manager, right-click the camera and select Update Driver.
  2. Choose Browse my computer for drivers, then select Let me pick from a list of available drivers.
  3. Select USB Video Device (if available).

Turn Off Power Management for Camera

Sometimes power management settings can cause issues with drivers. Try disabling it for the camera:

1. Go to Device Manager.
2. Right-click the camera device and select Properties.
3. Under the Power Management tab (if available), uncheck Allow the computer to turn off this device to save power.

BIOS Update

Even though you’ve checked for BIOS settings, make sure the BIOS itself is up to date. Sometimes, newer BIOS versions contain fixes for hardware/driver compatibility issues. Check the HP Support site for any BIOS updates for your Spectre x360 model.

Driver Verifier (Advanced)

If the issue persists, you can use Driver Verifier to identify more detailed driver issues. This tool runs checks on third-party drivers:

1. Open Command Prompt as an administrator.
2. Type verifier and press Enter.
3. Select Create custom settings (for code developers) and choose Select individual settings from a full list.
4. Check options like Special Pool, Force IRQL checking, Pool Tracking, and Deadlock Detection.
5. Select Select driver names from a list and choose the problematic driver (iacamera64.sys).
6. Restart your computer. If a specific driver is causing the problem, Driver Verifier may help pinpoint it.

Disable Fast Startup

Sometimes Fast Startup can conflict with device initialization, particularly with drivers like iacamera64.sys. Try disabling it:

1. Open Control Panel → Power Options.
2. Click Choose what the power buttons do.
3. Click Change settings that are currently unavailable.
4. Uncheck Turn on fast startup and save changes.
5. Restart your computer and test if the BSOD issue persists.

I hope this helps.

Take care and have a good day.
