    reset bios to defaults in maintenance.
    what bios version ?

    a lot of these boards had issues on first generation for 3 months due to intel manufacturing issue.

    power supply also can go bad and its special small size.. u can test with open case with new bigger standard size power supply.

    i have one here that did the blinking orange power led .. tried my power supply and it works.. now i plugged in old and that works too.
