On Button Lights but QuickSilver Does Not Start

WHAT I HAVE: I have a 2001 Mac QuickSilver 733 Mhz whose hard drive died. I purchased another 40 Gig drive, a new PMU battery and another 512 meg card to add to the two 512 cards already on the machine.

PROBLEM: Reconnected the Mac and pressed the “ON” button which glowed for about 1 second and went out. The Mac did not turn on.

SOLUTION, PLEASE:
