Just did a new build. Everything seems to be running well, until about an hour ago. I heard some loud whining from the bottom front of my case. I thought maybe the front case fan was rubbing against something so I just unplugged it, still hear the loud whine but it's just every once and a while, I can't figure out why it goes off. Only thing in that area are two HDD's. One 6 month old Western Digital 250GB and one 75GB WD IDE that's many years old. Is this one of the HDD's dying on me? If so, I hope it's the old IDE drive because I planned to replace it soon...... Before I take it out I'll ask here, not sure what else could make that sound. Not pleasant sound at all.
(Edit)Just wanted to edit and say the sound is almost like metal grinding on metal. I can't think of any other way to describe it.
