Locate the SPI Flash IC (usually an 8-pin SOIC chip near the PCH/CPU). Use the boardview to verify that Pin 8 ( VCC ) is receiving +3.3V_SPI . If voltage is present but the system fails to POST, desolder the chip and re-flash it with a verified clear-ME BIOS bin file using an external programmer (like the RT809F or CH341A). D. Blown Charging MOSFETs
