Monitor is putting out a really annoying high tone
A couple of weeks ago, my monitor started randomly (?) putting out a very high 'beep'. Its not like a 'notification beep', but a monotonous long 'beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep', at a very high (all through your bones) tone.
Sometimes the beep stops when I switch my browserwindows to a site with a differently colored background (so when its beeping at white, it will stop at black, and v.v.), but sometimes it just goes on all the time.
I have no built in speakers, and the sound definitely doesnt come out of them, as its also there when my speakers are detached completely. I have thought of it being my soundcard, but my pc (not my screen) is on the floor now and i still hear the sound coming out of the monitor's direction, and it stops when i turn my monitor off.
It's a pretty old (5+ yrs) monitor, so maybe thats the problem, but maybe you know what else might be up, and if theres a way for me to fix it. Thanks for you time.

Re:
Sounds like you have a capacitor going bad. All monitors make a noise, whether the human ear can usually hear it or not. If it has gotten rather loud, I'm afraid your monitor is on its last leg. White is a hard color for a monitor, because the electron gun inside has to fire on all pixels, and of course black is easiest because it is just blank.
Some people I've talked to have had temporary relief or prolonged the life of their monitor by keeping it on lower resolution in order to make its job a bit easier. Besides that, there isn't too much you can do.

In Windows 7 ,Try the Power Options in Control Panel. Set to High Performance, select Change Plan settings, set Sleep to never, select Advanced Power settings, scroll through the Advanced Power settings, set Sleep and Hibernate to Never and Power Buttons and Lid to Shut down. Always shut down and unplug the Laptop when not in use to prevent damage due to a power surge and a possible Fire hazard IF the battery malfunctions. Not to mention unnecessary wear on the components.

The HP All-in-One provides three levels for adjusting the Ring and Beep Volume and the Phone Line Monitor Volume.
The ring volume is the volume of the phone rings. The beep volume is the level of button press and error beeps. The default Ring and Beep Volume setting is Soft.

2. Press 4, and then press 4 again. This selects Basic Fax Setup and then selects Ring and Beep Volume.
3. Press to select one of the options: Soft, Loud, or Off.
4. Press OK.

Can you use it?If you can the internal power supply might be going or the inverter board.One way to confirm this is listen closely to the monitor if you hear a sound almost like tin foil in the wind the internal power supply is going,if not you are good.However If you can go into the menu of the monitor try doing a factory reset.This may fix it.
good luck
If the screen is getting dim to the point where you can't read it, it might be due an intermittent backlight. If this monitor is really only three weeks old, you might consider returning it to the store where you purchased it and exchange it.
If the picture is Reddish either at top or bottom It could be the backlight failing.If you are technically able you maybe able to Replace the CCFL backlight.
