This sounds right to me - I had a similar problem, and DT&T and MCE
couldn't fix it, although they tried checking the PRAM, changing the
Motherboard and changing the I/O board. I eventually sent it to
apple, who reformatted the hard drive and reinstalled the system
software (something I couldn't do because I couldn't get it to start
up at all), and it's been working for about a week now.

p.s. Thanks to everyone who made suggestions when I reported the
problem earlier.
