My computer monitor produces a head aching, at first with hissing sound
then followed by hi-pitch sound in diff wave lengths when turned on for
about 5 mins. I already having a migrain. Please help me. I already
changed its memory into a bigger size and even reformat my computer but
to no avail. So I just turning it off whenever I hear that sound and
just be back after 10 min or so and do my comp works... and that sound
will be gone for a moment only.
What could be the reason? My cousin suspected that it could be my monitor. Can it be repaired?

Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.
.......Does the sound disappear when you turn off the monitor? If so then it's the monitor, (hardware problem), not something you can solve by changing the tower around.
If it's under warranty, call tech support and have their input or take it back to the store. If it's old in the least a repair could easily be just as much as a new or used CRT. If you cannot afford a new one. There are plenty of people unloading there CRTs while they are upgrading to LCD and there is not a big market for used ones.
