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.

Likom lcd autonatic shutdown

Sounds like a hardware issue. Make sure your settings on your computer are not causing it.
If its not your settings then it is a hardware issue with the monitor which sadly means you will have to send it to the manufacture or someone who does hardware repair.

PC Monitor producing hi-pitch sound

.......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.

The monitor cant view video

To use the external vga connector of a laptop, you have to activate it. In many notebooks it is Funtion and F7 (Fn-F7). In your notebook it may be F5 or F6, look for a monitor sigh in the F keys. The activation may sometimes rotate in sequence , ie, External + LCD, LCD, External... and so on.
