Explanation

The front panel header connector (also called the system panel connector) connects the motherboard to the power button, reset button, power LED, and HDD LED. If this connector is wired incorrectly-for example, if the reset switch pins are shorted or misaligned-the system may behave erratically, power off unexpectedly, or produce unrecognized beep codes. Since the technician confirmed all BOM items are installed, the issue is likely a connection problem rather than a missing component. Thermal paste (A) and auxiliary GPU power (B) are common new-build mistakes, but an unspecified beep code paired with an auto-shutdown within seconds more specifically points to a front-panel wiring issue. The I/O shield (D) is a physical fit issue and would not trigger beep codes.
