MSI KT4V Mainboard and Alarms

Anyone familiar with the alarm sounds, and this is extremely hard to describe by using text, but here's the situation. I sent a previous post about this mainboard and Athlon XP 2400+ CPU not to long ago, thank you guys for the suggestions and comments. Upon POST of the, of course we're dealing with standard BIOS settings here, so it doesn't detect the correct speed of the CPU, not really a problem at theis point as a BIOS update will take care of that. I enter my date and time, it detect the memory and both the HDs nicely. The temps are pretty stable at 100 degrees F. I want to pretty much leave all the settings default except for a couple of things until I can flash the BIOS and then I'll make the major modfications, I save settings and reboot. The PC reboots, flashes the POST screen very quickly, goes blank and an audible alarm sounds, similiar to a British police car. You then have to clear the CMOS, do your settings again, save and reboot and it does it again. I'm not altering any voltage settings to the CPU or memory to elliminate that variable. I'm wondering has anyone else heard this "alarm" and what did it mean. I'm narrowing it down to CPU or memory.
