Question : Problem: Computer making strange beeping noise when under stress

My computer is making a fast  beeping noise( that repeats with no end) when I am gaming.  It is a new computer with vista.  It only seems to happen when I stress the computer.  It doesnt cause the computer to turn off or display an error message.  Here are my specs:

Intel Core 2 Duo E6550 2.33Ghz, Asus P5K-V MB, 2GB Kingston DDR2 Ram, 32GB Western Digital Raptor 10,000RPM Sata Drive, Chaintech 8800GTS 512MB PCI-Exp Video Card, Antec NSK4480B w/430 Thermaltake PSU, LG DVDRW, Microsoft Vista Ultimate
