    Is Gigabyte Motherboard Defective ?
    I have installed a Gigabyte GA-EP43-UD3L, an Intel E6750 Dual Core 2 CPU. GeForce 8600 GT and 3G Memory.
    The problem is that when I start the PC the CPU Fan will not work and neither will the fan connected to a System Fan Header. The four lights come on and stay on below the CPU fan header also there is no acknowledging beep.When attached to Monitor -there is no pic or noise. All connections treble checked and seem OK. Checked the memory and no change if any removed.
    Has anybody got a clue what is causing this, I have built a few PC's but nothing like this .

    Check:
    • Fans work independent of being connected to the board.
    • Fans are of the speed control variety and the function and order of the leads match board header pins.
    • Power supply.

    Then:
    Do a complete rebuild from square one.

    Finally, if problem persists:
    Try another board.

    Might also give Gigabyte a call. According to the board's documentation, those LEDs indicate CPU loading and the board has some whiz-bang power saving features. Sounds as if board is partially on, if that's possible. *shrug*
