Hi everyone and this problem has been bugging me the whole day! I even spent 4 hours of my day just to fix this. Now lets get to the problem, my problem is that my Powermac G5 DP 2.0GHZ June 2004 boots up and the fans do their normal thing of reving up then down, after that the dvd drive reads my Mac os x Tiger disc for a while then it stops then the fans just speed up and up until its like a prop plane. I have taking the machine apart expect to the the cpu as the little pin I can't get out so the cpus are a no go for now. I have taken out all the ram and tested them all and I use a ADC connector for my monitor as I got it with the Powermac G5. I got this $40 as it was a good deal please help I don't want this in the skip! Also the power led only turns on when I press the power button down and there is only 2 leds the red led and power led.
