    No, it will not start. When you push the power button, I get one solid high pitched tone. It lasts for about 15 seconds, stops for the same, and repeats

    When, exactly does the noise occur? Do you get to Windows?

Could be the hard drive, a fan, or the power supply. Try unplugging the hard drive, turning the computer and using a finger to stop a fan (careful though, some can go very fast!) to narrow it down.

Hi,
If this is a desktop computer then chances are that one or more of the capacitors are failing. This will be high pitched sound that you can hear.

If this the case then you are looking at a new motherboard.

If you are talking about a laptop then please post back with more details.


Regards.

With a piece of wood or plastic hit the flyback with the monitor turned on. If you note some change in the noise. Replace the flyback.

How do i turn off the high pitched frequency noise


If what we are talking about here an old model of monitor that has a bulky back, the high pitched frequency is caused by other electronic devices such as your speakers.

- Relocate your speakers away from the monitor
- do a factory reset on all settings on the monitor or if possible, do a degauss.

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.
