Motherboard making a high pitched squeal: solved

I just started trying to rebuild my game machine this morning. I haven’t used it in about a month…since I took the hard drive out. I just put in the new drive but when I connect the power all I get is a very piercing high pitched squeal.

I’m trying to figure out from the MB manual what this means but I thought maybe one of you would know off the top of your head what’s going on.

:?

[EDIT: Didn’t have the power supply plugged into my GeForce 6800]

Of course now I can’t get my SATA raid to work but oh well.
