PowerMac G5 won't start; Power on light blinks.
My PowerMac G5 dual processor stopped working yesterday. It had been behaving unusually lately with frequent freezes that required it to be turned off and them restarted. I have removed both internal drives and them are both working fine. I also blew some of the dust inside built-up around the electronic boards and the internal fans. In addition I also pressed the reset button to see if it would solve the problem. It still won't start.
As I press the power on button to start the computer I notice that a few seconds later the power on light starts to blink. Not the type of blink that alternates between light on and light off. Instead the light will vary its intensity between low and high. It blinks three times than an short interval follows. Then it blinks three times again followed by an interval. And it continues following this pattern.
Any ideas of what it might be ?
Thank you in advance.
