1994 Chrysler Le Baron Whining noise shortly after driving

Noises problem
1994 Chrysler Le Baron 6 cyl Front Wheel Drive Automatic 110k miles

I noticed that recently, shortly after I've been driving my car for a bit, it begins to make a high-pitch whine. The whine sounds like its coming from my power steering since when ever I turn the wheel after the sound has started, that it changes pitches, but the sound continues even when im driving straight down the road. I checked the power steering fluid and its fine, but as a college student, I don't want to spend money to fix my car unless I know whats wrong with it.
