High pitched noise turns on when I open things in windows.

[CrewXp]

Hey, I have a problem. I turned on my computer today, opened up a folder and a high pitched noise started ringing from my case somewhere. I'm not sure what part it's coming from as its hard to hear exactly where something is when it's a high noise.

But it happens every time I load a program or open a folder. When I close them, it stops.

Here's whats in my system:
CoolerMaster Stacker t01 case with this stuff:
E6600 Intel Processor
WaterCooling Setup (Ask if you need info)
Corsair 1Gb Memory
2 Raid-0 SATA hard drives (Seagate 320Gb)
Game X-Tream 700W Power Supply
ATI X1900XTX 512Mb Video Card
Creative X-Fi Platinum Sound Card
Hauppauge PVR-150MCE Tv Tuner
Asus P5w-Dh Mobo

Thanks alot.

Bad hard drive maybe?

does it sound like a PC speaker or a mechinaical or electical sound? Could be a PSU dieing.

Take off the side panel and try to zero in on noisy area if possible.
That's my suggestion first. Next comes the actual search, by turning on application.
Good hunting.

is it like a 60hz hiss you sometimes hear from transformers / ballasts (but higher pitched)??? if so then its most likely the psu, sometimes the mobo, ive seen both, but psu is by far more common... but it sounds like its only when you open a folder it might be mobo...

oh dur.... check your monitor, that may very well be it... different colors may cause the hiss, usually its cause of different sync freq....

then again i could totally be wrong about it all...
