Hello, I bought this Mac G5 1.8 Single I believe in 2003. She was working perfectly and suddenly a couple of years ago she started to increase the cooling fans. Later when there was a power failure from the authorities she couldn't start first in a day and then maybe in a couple of days later or a week. Now, I have a new computer but still want to recover a couple of things from her and try to fix it so I can use it for another minor stuff. She starts when I press the power button, I hear all the machine starting but I don't hear the chord sound telling me that she's booting. Then the white light in the power button starts to flash. The monitor stays black. What should I do? What is happening to my computer?
