If it was the battery then there would be a warning at boot saying checksum error etc and to press F1 to continue, so i dont think its that.
I've been looking throught the manual for your mobo, can't find much. I did notice an alarm function in there, is that turned on? Also your mobo comes with PCprobe software so it might be worth using that to monitor your hardware to see if it shows anything.
Have you changed any BIOS settings at all, or are they all on stock settings? Might be worth resetting the CMOS just to see if theres some sort of rogue setting causing the beep.
