Look more like a glue logic problem since its charge well and boot up normally after a total power down reset state and fail to do so subsequently after the first power down or reboot. I had one motherboard with an Intel chipset that exhibited similar symptoms after I somehow managed to corrupt the BIOS with a modified custom one. Even after I flashed back the original stock BIOS externally, it's manage to boot normally the first time but subsequent boots after restart or power down the motherboard itself manage to corrupt it's own BIOS.
