Since you've already replaced the hard drive, did you try disconnecting the optical drive? I've had a bad optical drive keep a computer from booting properly.

"I have seen this before in powermac g4's. In The end, a graphics card swap fixed it. the graphics chipset is integrated on these macs, so most likely, you may be stuck. have you tried resetting the PRAM (Boot holding Command-Option-P-R, until it chimes 3 times) this might solve the problem, you could also try re-seating the heatsinks on the CPU & GPU. though these computers are a pain to open (i have an ibook G3, and i had a very hard time upgrading the drives) Good luck, if you boot into verbose mode, it will most likely freeze after almost finishing, and the same with single user mode unfortionatly. (I could be wrong, it's been a while)

good luck,

Chris"

my moms MacBook does the same thing sometimes... you press and hold the power button when it stalls there and then when it turns of turn it back on
