Strange Beeping Problem

[Crono]

Whenever I open Graal, my computer (I can't tell which part) starts to make these funny beeping noises. Not really the beeps you're thinking of, more like soft "extended" beeps that sound like lasers.

The only explaination I have for this is my high cpu temps + graal taking 100% CPU. I don't know, someone tell me whats wrong..this isn't normal.

Specs-

AMD Athlon 2700+ XP 2.17ghz
256DDR PC2700 Original Apacer
ATI Radeon 7500LE 64DDR PCI
Windows 2000 Pro

These are the only things that would really have anything to do with it..
