Have you checked all the jumpers etc??
That powerleap deal sort of adds a little confusion....did it come with instructions about fsb etc.
Go here and download the manual and check all the jumpers..there are several if I remember

Are you saying you NEVER got it to boot? Or you installed XP and THEN it wouldnt boot??
You might have to try to disconnect everything off the motherboard except the cpu, vid card, one stick of ram and try to boot like that to see whats up.
Disconnect floppy cables, ide cable, modems etc.
