Strange Siren Sound on Boot

  1. Hi All,

    I bet that this has been covered before and I have done my looking around
    on the net before posting, without much luck tho it has to be said

    Just got an ASUS a7n266 - vm board rev 1.05 and when I power on I get a 2
    tone beeping sound akin to a Siren.

    Ive ripped the entire mobo out of the case, put it on a test bench, put a
    different power supply on it, tried the settings for memory and cpu
    frequencies and I still get a siren sound.

    Strange thing is that when I boot up the first time I get nothing, the next
    time after ive switched it off I then get the siren effect.

    Any help would be greatly apprecaited.. Thanks

  2. Dead board, it seems. This siren sound is generated by the monitoring
    chip and usually indicates a PSU or mo/bo failure.

    It's not the sound, when you enable
    chassis intrusion is it? (If your mobo
    supports this). This is a jumper on
    some motherboards. Which according to this
    manual (but not for your mobo). sends a high-level
    signal. This goes off if the jumper isnt shorted.

    If you remove any chassis component/s. Did
    it go off, with the case on or off? on i take it?
