It is a Samsung 15inch and is about a year old. What is happening is,, about a week ago I noticed it was making ahigh pitch squealing noise. I finally moved it to the other side of my desk thinking it was getting interference from my cable modem. It stopped. I moved it back and it did not start back up. Lasted about a week and it started again this morning. I moved it again and it continued. I can turn off the monitor and it stops. What is strange that When it is shutting down it stops when the windows splash screen goes away and when it isbooting does not start till the splash screen appears. I took off the background and disabled everything I could think of and still the same. Could it be the modem interfering? Is it just going out? I am going to try and give a layout of my desk so use your imagination
my desk is out about a foot from the wall with a shelf on the left side level with the desk and another one above that one. The top one has my scanner. The one that is level has my printer and the modem. My monitor is rightr next to that one and my tower is in the right corner. I am trying to rearrange the desk now but wanted some advise on the monitor. Does there need to be any certain space between components? God all this to find out if the monitor is going out. Thanks.

A cable modem is not likely going to be causing any interference with the monitor. The things you have to worry about are sources of strong, rapidly changing magnetic or electric fields. Amps, speakers and possibly fans sitting on the monitor are generally the only devices that cause trouble. However, these are generally limited to visual distortions and discolorations.
Judging on what you've said, I'd suspect the monitor but that's hardly a professional assessment.

Gettig no video problems. Oh heck doesn't it figure when I make a plan for something to go wrong. Thanks for the response.

Highly unlikely that any of your peripherals are causing the problem.
If it's a fairly high-pitched whine, then your horizontal scan circuitry and/or flyback transformer are on their way out. In the early stages of death, turning off the monitor allows the components to cool down enough for the problem to go away. The noise probably didn't stop because you moved the monitor, but more likely because you turned it off when you did so.
The reason the noise coincides with the launch and exit of the GUI is that before the GUI is started, after it quits, and when you are running in text-only/command line mode, your video video system is usually operating in a basic VGA or SVGA mode, which is less taxing on the circuitry. It isn't until the GUI is running that the system kicks up to higher resolution/scan rate settings that you specified in the display properties.
Since your video card drives the monitor, and feeds it not only the color and brightness information, but the actual scan rates (horizontal and vertical) as well, it is possible that the video card is faulty. If you can, put the monitor on another system (runnning at the same or similar video settings) and let it burn for a while. If you still get the noise, it's the monitor; if you don't, it may be the vid card.
If it is the monitor, and it's out of warranty, it probably isn't worth repairing as the price of 15" monitors is not that much more than the flat rate most service companies charge to do the repairs.

Lowering the refresh rate might prolong life a little. Talking about refresh rates, you aren't by chance using a higher refresh rate than supported by the monitor? That is not a good thing and would cause the problems you're having. You might also want to make sure it is getting plenty of cool air and the room it occupies is not too warm.

I have a monitor that has a similar problem. I believe you have a leaky fly-back coil. Keeping the humidity in the room down will allow you to keep using the monitor. You could attempt to seal the coil using a product made to shield HV such as corona guard but I would not recommend spending much repairing the monitor. 15" monitors are less than a $100 so I would replace it before spending money to repair it.
