I agree with the power supply suspicion, and there is one easy thing  
to check regarding that. The power cords on iMac require a little  
extra force to be all the way inserted.

Have you checked that? The powercord 'collar' needs to be flush with  
the back of the iMac.

May not be the issue, but it is cheap and easy to check.
