I had a similar problem. I have an early (rev 4.2 motherboard) A2000, and 
occasionally It would develop a problem where is wouldn't boot without
GURU'ing during the process (you don't really say what happens to you).

I could pull everything except the disk controller with no effect. Pulling
the controller immediately eliminated the problem.

In my case, it resolved to finding a board placement arrangement that would
work. With the controller in certain slots I would have the problem, in
others I don't.

There were reportedly problems with some slots on some early machines. You
didn't say you had tried this, but if not you might try using other slots
to see if the problem goes away.

If the board works in other machines but not in yours, it must be your machine.
The first place to look is where the connections are made. After that, you're into
motherboard repair.
