It looks like you have a faulty motherboard, the whining sound is the diagnostic beep from motherboard doing just an abnormal sound as the motherboard is getting jammed and turning off.
If you have a replacement CPU that mounts into your motherboard's socket, test it out.
Start the motherboard with a minimal set of devices:
PSU
Video adapter if needed.
CPU
CPU FAN
Just 1 well tested RAM module.
Unplug all motherboard connectors apart PSU connector, and start button (unplug the rest) connector.
If it still does not complete post and turns off, then you have a faulty motherboard.
If the Motherboard alone stays on, then it is probably a faulty drive, a faulty ram module, a faulty pci device, or if the system started to load, a defective system.
Dear Sir/Madam,
This could be a few different things:
1. Can you see the bios screen (any video display?)If not, check the video card (re-seat or replace it).
2.
The fan shutting down, if this is a laptop computer with the newer
style of processors, it shuts down by itself when the computer doesn't
need it. When the computer get warm, the fan kicks back on by tempature
controlling.
3. If not the above, then you could be looking at a
Mboard failure as to not accepting the correct voltage to the fan. Most
computers will shut down or not load without correct voltage.
4.
Also, this could be linked to bad boot.ini file on the OS. Making it
unable to load the start up files. Have you added any new hardware
before the crash? If so, systematically take each one it out and then
try to reboot the machine.
Thanks
Good Luck
The high-pitched whine may well be coming from a bad bearing in your CPU fan. Most systems will shut down immediately as soon as they detect a CPU fan failure (and usually with no warning or error messages). A system fan can also cause this, but with most BIOS, you'll at least get a message.
Cheers
Nick
The high pitched sound you are hearing is a capacitor getting ready to blow on the motherboard, have a look on the motherboard for any swollen capacitors also ones that look to have melted plastic onto the board, the faulty capacitor will look differnent from the rest. you can change the capacitors bit it doesn't always work, meaning a new motherboard
hope this helps
regards
agreed nickstorm, could be the CPU fan also :)
Briefly, the invention is based on a discovery that a capacitor in the
initial stages of deterioration will generate high-frequency signals as
dielectric breakdown occurs. The lower limit of such signals is in the
frequency range 50 to 200 KHz.

i stand my original prognosis, here is a more detaled description
High pitched noises often are caused by failing capacitors (think how a
camera flash sounds when it powers up and cycles; that's the capacitor
you hear). They can be on the motherboard or in the power supply. With
CRT-equipped machines, the transformers can vibrate also. This may or
may not mean there is a problem.
You can usually see residue from leaky caps if you look on the circuit
board. If you're not handy and are not familiar with standard safety
procedures, leave it to someone who is. In particular, any Mac with a
CRT has lethal voltages stored inside.
regards again

You mentioned that you connected another hard drive on the computer? Did you check the jumper settings on that hard drive? Make sure that it is set to slave or maybe try to remove the jumper settings on that hard drive that you last installed on your computer. Try removing the hard drive to check if the problem is really on the hard drive settings.
Remove all the cards from the mother board and then reinsert it properly and then check.also check out the memory chip is proper or not.(RAM)
any of the connection is loose on the mother board so the noise is comming.
remove the RAM from your machine and try to clean the golden lines on the RAM with a pencil rubber so if any dirt stuck on it will be cleaned and then insert it should work.also if u have another RAM with u replace the RAM and then checkout.

All components are correct and have worked correctly for over a year. Removed and reinserted cards and memory as suggested. Problem persists. System shuts itself down about 15-20 seconds after drive checks and familiar first beep. Nothing on screen.
