Hi, just noticed now that the lower corner of the screen where windows toolbar is (specifically, the clock) fades to a bluish-purple hue. The perimeter is a triangle fomed by the screen corners and the AM/PM of the time... Isn't it supposed to be a consistent bright blue? What is wrong and how could I fix it? The problem has been persisting for almost two days.

Monitor is an AOC 5en CRT according to the manual and it has been working fine until now. Haven't changed any settings recently aside from making the resolution to 800 then to 1024 to check if it will disappear.

Are you able to try another monitor on the computer, or try the monitor on another computer?

I'm sorry but I don't really have any idea what's causing your problem. You could always try updating your graphics driver.

Do you have a speaker sitting near to this monitor, or anything with a large magnet?

Check the monitor owners manual and degauss the monitor, after you have moved speakers, etc at least 24" away.

Uh oh.. I have one speaker on top of the CPU and the other on top of the monitor (they are logitech s100 speakers only) and they've been there for like 4months now.

Why, what do they do?

Thanks for the link! But what I also meant was what do the speakers do to the monitor? and where should I move them?

the magnetic field of the speaker affects the crt. it alters the electron beam just enough to change which phosphors are illuminated.

Is the picture in your avatar supposed to look a bit "ragged"? I mean that, to me, it seems to have some distortion. If not, there may be an issue with your video card, drivers, or operating system that could be causing this.

Not only do the speakers affect the monitor, the monitor affects the speakers - the magnets cause distortion. Just move them away a bit.

I had a really nice but very old Sony Trinitron that somebody gave me - it had severe color distortion that was noticeable more on some backgrounds than others. It cleared up eventually, before it failed completely and would no longer switch out of power saving mode.

As has been said, it would be very easy to swap monitors to see if the problem persists - the "permanent" magnets in the monitor will slowly fail over time and it may be failing. If the problem persists, then I agree it may be a video card issue.
