Fried RAM and Toasted Board
Mac Pro Dual 2.0 GHz 3GB RAM 320 HD
This one has had me busy for a couple of days. Came in with three blinking lights on the power button and kernel panic on start up. After testing for an hour it would not boot at all. The machine had two 1 GB sticks and four 256 sticks. After extensive testing I found all the sticks were fried. Replaced RAM with two good 256 sticks of my own. Switched hard drive to a known good system and it booted to the kernel panic screen again. After testing for another hour it fried my RAM and I get no boot. I ask this question because I don't know if the power supply might be involved and I don't want to replace the motherboard just to have it fried again. I haven't seen a machine that keeps frying RAM before. Suggestions?

This machine should have diagnostic LEDs. Did you check them?
Interesting question--can't wait for the solution. +
