Command Center for Aurora 7500

I just picked up this beast of a computer and after searching the net for hours trying to find out the model and if it should have LED lights or not, it should. I have none. The Alien head on the door is missing the bulb but the LED lights that I should have on the front grill are not on. When I open her up I can see a really bright red light coming off the bottom left corner of the mobo but no lights can been seen on the outside. Pretty much I need to find the Command Center for my computer Aurora 7500 it's the one with the AMD 64. Every image I've seen of my computer shows the lights in the front grill and in the Alien head. So where can I find the drivers for it? Dell's website has been no help at all every link I find sends me to a page saying sorry try again later.

EDIT. When I do happen to find one I get a error message 1633 something about my processor. When I go in to my system properties it says AMD Hammer Family processor model unknown. Is there a way I can get my computer to  I guess read my processor?
