The POST-Check Protocol
-
Standoff Installation
Action: Must ensure metal standoffs are installed in the case for every screw hole on the motherboard and only those holes. Why: Standoffs lift the motherboard away from the metal case, preventing a fatal electrical short that will destroy the board when powered on.
-
The I/O Shield
Action: If your motherboard doesn't have an integrated I/O shield, install the separate shield into the case before mounting the motherboard. Why: Forgetting the shield means you must unscrew and remove the entire motherboard later, which is a massive waste of time.
-
Pre-Install Components
Action: For ease of assembly, install the CPU, CPU Cooler mounting brackets, RAM, and M.2 SSDs onto the motherboard before placing it in the case. Why: Working outside the case avoids cramped spaces and makes critical installations (like the CPU cooler backplate) far simpler.
-
Front Panel Headers
Action: Consult the motherboard manual and use the tiny front panel connectors (for Power/Reset buttons and LEDs) before installing the GPU, or buy a front panel header block to connect them as one piece. Why: These tiny pins are difficult to access once the large GPU is in place, and incorrect wiring means your power button won't work.
-
The Power Duo
Action: Ensure both the large 24-pin ATX power cable and the 8-pin (or 4+4 pin) CPU power cable are firmly clicked into the motherboard. Why: The 24-pin powers the board, but the 8-pin is the dedicated line for the CPU; skipping the latter means the system will not boot.
-
RAM Seating
Action: Press the RAM sticks firmly into the correct dual-channel slots (check the manual for slot numbering, usually A2/B2) until the latches at both ends click securely. Why: Improperly seated RAM is the most frequent cause of a new PC failing to POST (power on self-test).
