Meaning of 2-tone warning sound from mb?

I have an Asus K7M motherboard that is putting out a cycling, 2-tone warning tone soon after powerup. The motherboard manual does not describe any of the warning beeps/tones.

Does anyone know what problem the motherboard is signaling about?

thanks,
Don

Do you get a video signal??
If not check your video board, make sure it is seated properly.
If this is not a new MB or video card install then your board could be bad.

Check your memory also while you inside that it is seated properly

2 beeps - Parity Circuit Failure

Try reseating the memory first. If the error still occurs, replace the memory with known good chips.

I'm getting normal video and (as long as I dare to push it) the machine appears to operate normally.

You are getting normal video without reseating the card?

If so there might be a setting in the BIOS for the video that could be causing this proplem. If this is the problem then what BIOS version do you have?

Is your CPU fan spinning up easily? some motherboards have a two tone alarm for fan failure. Your fan might be appearing to work, but have trouble getting going if it is over a year old. Plain bearing fans don't last long and often cause trouble, ball bearing ones last longer. Sometimes a drop of oil will cure it (lift the label and drip some in the center hole)

Oh, am presuming the fan does spin up at some point since you would be noticing a lot of crashes if it wasn't turning at all, you may be getting a crash every day or so if it isn't turning as well as it should be.

Aha! Tone was a BIOS warning indicating voltage was set above default.

Thanks for your help,
