Power button flashes

Specs: Windows XP
Im having a problem with my Dell monitor computer is 4 years old. Went to turn it on the monitor turns on fine makes a high whine noise (never did before) shows my boot up screen but when whining stops it goes black and the green light that shows the number of the input and power light both stay green and start flasing. Now if i stop all power let it rest all night with no power to it turn it back on it works fine but if it goes into sleep mode and i wake it back up even if only a second it does it again, just want to know if its time for a new monitor

I see nothing in that that mentions the whining. The whining can indicate a problem with the monitor OR the computer you have it connected to.

Your video symptoms - "...it goes black and the green light that shows the number of the input and power light both stay green and start flasing."
and
"....Now if i stop all power let it rest all night with no power to it turn it back on it works fine "

can be caused by either a faulty monitor or a faulty computer, since both the monitor and the computer would have cooled to room temp. The blinking green led or number or letter a lot more likely indicates the monitor is receiving no video signal, rather than it indicates the monitor is faulty and not displaying the video because the monitor is faulty.

"...if it goes into sleep mode and i wake it back up even if only a second it does it again"

That can merely be because you don't have the main chipset drivers and info included with them loaded for the computer's mboard in Windows. The info about the main chipset is needed in order for Windows to know how the main chipset / the mboard supports ACPI features - including Standby, Hibernate, Restart, wake up features in the bios, etc, etc. .
.......

Try the monitor with a different computer.

If you get the same symptoms with a different computer, your monitor is faulty.

If you DO NOT get the same symptoms with a different computer, then the problem is with your computer.

Well if i unplug the minitor and turn it on to do the self test it does the high whining noise and when it warms up and the whinin stops it goes black and the power button and the number to indicate which vid mode it was in starts blinking. It will continues do it untill you cut the power to it no matter how long you let it go

Check for bent pins that are touching each other in the monitor's video cable plug. Other than that possibility, your desription sounds like the monitor's circuits are damaged.

CRT monitors are larger, heavier, and use more power, but the latter CRT monitors are superior to almost all LCD monitors as far as the display is concerned.
LCD monitors and displays always have a "native" or "optimal" resolution - a resolution at which they look the best - at all other resolutions they don't look as good, the most noticeable thing being the text on the screen does not look as clear. CRTs don't have that limitation.
LCD monitors and displays have a xxms rating - xx milliseconds - the minimum time it takes for the display to change to the next frame - the latter CRTs are much faster regarding that. Fast moving video looks much better on the latter CRT monitors.

And - a CRT monitor's useful display life tends to be a lot longer than a LCD monitor's.

Dell doesn't make the monitors it sells - they are supplied to Dell by a major monitor manufacturer, and merely have Dell labeling (branding) on them .

When you buy another LCD monitor, I recommend you buy a major brand - the extra you pay is well worth it. E.g. a friend of mine has two Samsung models - an LCD monitor, and an LCD combo TV / monitor (it has a VGA input) - they've been on 24/7 most of the time for about 5 and 4 years respectively, though she has been using a blank screen saver for the past year or so, and both still work fine.

If you have the extra bucks, the displays with the longest expected life are the plasma displays, and the relatively recently released LCD LED displays that use LEDs to supply the white light behind the LCs rather than (a) backlight(s) ( the backlight(s) burn(s) out eventually).
