If you're 100% sure the monitor is good, the problem is that it's not receiving a video signal from the tower. And that problem could be due to a lot of different things. That's as much as I can tell you based on the limited info your provided.

Does it actually say "no signal" on the screen?

Always pop back and let us know the outcome - thanks

Does the monitor actually power up; and if so does it go to a standby state? (Usually current monitors/displays have a green light when receiving a signal - and orange when not - which represents standby.)

Have you tried another vga cable?

Have you verified the monitor "is" OK by testing it - connecting it to another working computer?

Also have you verified/checked the vga card is securely installed into its slot? Do this of course with power off (and ac cord removed).

If you are using a separate video card most likely it has either worked loose, the edge connectors want cleaning (use soft pencil eraser then pop card in and out a few times) or the card has failed.

I'm assuming that you never ever see anything else on the monitor but the "no signal" message.

Always pop back and let us know the outcome - thanks

Please turn off your caps lock, it is like shouting.
Please list your system specs (make/model) or a details component list.
Please give us a brief history. Has this combination computer/monitor worked before? Recently? Has there been any recent changes in hardware or software? Have you been having any recent problems with the system? Was this a normal waking or starting of the system or was there a sudden shutdown or restart involved? Has anyone recently opened or worked on the system? Are you seeing any colored lights from the monitor or has there been any screen messages at all? Have you tried unplugging the power to the monitor, waiting a minute, and plugging it back in (look for any changes in lights or screen massages)? Have you tried manually holding down the power button on the computer to make sure it is fully shut down, unplugging it for a minute, plugging it in and starting it and seeing if there is any change in the monitor or what it shows.
More details and info is needed for more specific suggestions.

You have to be a little bit crazy to keep you from going insane.

Sexytech, you think your computer is fine because when you start it up you see the LEDs flash and hear drives and fans spin up. But assuming your speakers are on do you hear the windows startup sounds? I'm guessing no, you're not getting any of that.

A power supply has to provide several differnt voltages at sufficient current in order for a computer to work. The fans, drives and LEDs only need 5 volts for the LEDs and 12 for the fans and drives. Likely either the power supply isn't providing what's necessary or the problem may be with the motherboard.
