 Alex,

	You are quite right that there is no relation in memory size and power
supplie failures. The original poster has several options for his problem. One 
of the more expensive options is to take it to an Apple repair person. The 
only benefit that it will give you is a board that is better than the one that 
came with the Mac. This is because Apple's quality control on the repaired parts
is better than the control on original manufacture.
