All-in-One PC Windows System: startup application conflict. Third-party software loads early and interferes with a device or Windows shell.

The distinguishing clue

The fault disappears in a clean boot or safe environment.

Checks before an assessment

Note whether the built-in display, camera and audio fail together or whether Windows itself stops loading. Remove only nonessential external accessories with the computer shut down.

Stop point: All-in-one hardware can contain mains-power sections, so software diagnosis should precede opening.

Workshop confirmation and repair

Device-level check: Compare firmware, recovery, another account and external peripherals before opening the display housing.

Targeted check: Disable startup items methodically and identify the change that restores operation. If confirmed: Remove or update the conflicting program and restore normal startup gradually.

Repair boundary: Repair the confirmed software layer after internal hardware and storage checks agree.

Related cause to rule out

When the problem begins immediately after restart and recovery options may appear, also consider All-in-One PC Windows System: failed operating-system update before choosing a repair.

Checks after the work

After repair or replacement, check startup, display, camera, audio, updates, sleep and shutdown.
