Hard Drive and video board set-up

Hello,

I recently needed to replace my hard drive. A friend helped me, and during
the process I noticed he connected the ribbon from the motherboard directly
to the hard drive. However, the old configuration, I believe, had the ribbon
cable connected to the hard drive and the video card. With my current
set-up, I do not have any cable connected to the video card [ ATI Radeon].

This is causing some problems with the overall PC operation, including not
shutting down. It just re-boots. Because of this, I unchecked the
"Automatically Reboot" option. Then when I attempt a shutdown, I receive the
BSOD. Within this screen, it refers to an ATI3duag.dll, which leads me to
believe it has something to do with my video card not connected.

Can anyone please tell me how to properly connect my ribbon cables to the
hard drive along with the video card?

Thank you,

Vince
