A POST error code of 1xx indicates a problem with which component?

A POST (Power-On Self-Test) error code of 1xx is specifically associated with issues related to the motherboard. During the startup process, the POST tests various hardware components to ensure they function correctly. A code in the 1xx range determines that something is amiss with the motherboard, which is crucial since it connects and allows communication between other components.

Since the motherboard is fundamental to the operation of a computer, any faults detected here can lead to a failed startup. This could involve problems with the motherboard's circuitry, power delivery, or other integrated systems that control core functionalities. Understanding this allows users to focus their troubleshooting efforts effectively on the motherboard, as opposed to other components like memory, keyboard, or video adapter, which are indicated by different POST error codes.
