High Pitch Chirps from Tower

Specs: Vista 64 bit, q9450 4gb
Hey all, need some help.

when I boot my computer everything is fine until I reach OS desktop then I start to get high pitch chirps from somewhere in my tower NOTE- ONLY happens when I reach the OS, never in BIOS or before hand. The chirps are on and off with 3 seconds or so between each one, they are very quiet but penetrate due to the high pitch. I think it might be my PSU but it's a new and only had the system for under 2 months now.

System specs-

780i ASUS striker II Mobo
Nvidia 9800gtx
4gb DDR2 1066 ram
Thermaltake toughpower 1200w PSU
and a Vista 64bit OS

Have you checked your system temperatures? It could be a thermal alarm.

"Temperatures are fine"

Care to back that up with some numbers? System temp in the 30's, CPU temp in the 40's (at idle)?

Do you have ASUS PC Probe installed? It generates an audio alert if one of the settings (temps, voltages, fan RPMs) is out of range.

The only time I have heard a really high pitched sound like that, it turned out it came from a dying Maxtor 80gb hard drive on a friend's computer.
It wasn't long after that the drive could not be accessed at all - a day or two.

Check your hard drive with the manufacturer's diagnostics.

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.

I've got two computers that chirp, but only under Windows Vista. My P3 system as well as my wife's X2-4600 machine chirp/squeal under Vista, but they're silent under XP.

In both systems, the chirp seems to come from the CPU VRM area. Why these machines sqeal under Vista is a complete mystery to me.

This ain't ur momma's P3 system:
PIII-S @ 1.66GHz
2GB PC2700
AGP HD3650
Blu-Ray drive
Homebuilt 1920x1200 projector, Pixelworks HDMI controller
JBL receiver & speakers
