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

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?
