Dell Inspiron 1525 :: Making High Pitch Whistling Noise

I just wanna ask something about my laptop Dell Inspiron 1525 because recently it's making a high pitch whistling noise that i think is coming from the hard disk(not sure). But im sure its not from the laptop's fan. Whenever i turn on my laptop,a whistling noise starts,then the machine dies within 2 seconds,sometimes 5 sec. If i press the power button again, it wont start, its showing no life. Unless i replug the adapter and switch on again. But then again, it dies after a few seconds. Back to replugging the adapter again to switch on. Sometimes it takes 5 tries to finally open my laptop without dying. When it's finally done starting up, whistling noise would go away after a minute or two. Then it's like normal again. No noise, no overheating, no sudden shut off, no hang ups, etc. What could be the problem? I am using the charger provided by Dell and without a battery,just the charger directly from the laptop. Im certain it has nothing to do with the battery thing.

Im done with the diagnostics, no errors. I also tried releasing static electricity on machine by pressing the power button for 30 seconds. But still, the problem keeps on happening every time i power on my laptop.

Additional info: I tried removing the HD this morning and use a linux live usb. but still the problem and the whistling sound is there.
