Explanation
When replacing a motherboard, the front panel header connector block - which includes the power button, reset button, power LED, and HDD activity LED pins - must be reconnected to the new motherboard. If the power button pin connector is not properly seated on the correct header pins, pressing the physical power button sends no signal to the board, and the system will not power on at all. The question states all power and data connectors were connected, but front panel connectors are a separate set of small individual pins that are easy to miss or misplace. Options A, B, and D might cause issues after boot but would not prevent the system from powering on entirely.
