Rich I need your help getting that hard drive in my comp.

I put it in, aranged the little prong things in the back to run as a slave drive, and finally got my comp. to boot back up as normal with the new drive in. But I get the comp. started and its like its not even there.

I am 99% sure I have it hooked up right in the comp. But I dont know whats wrong. Any help would be great. Thanx alot man.
