Okay, I usually have my G4 running at least 12 hours a day. But recently, I went on 7 day vacation and the computer was computer was unplugged the whole time. I returned home, plugged it in today and tried starting it up but nothing happened. I tried starting it through the monitor the first time and the light on the monitor came on but nothing but nothing else happened, the cpu didn't start. Then I tried starting it up from the cpu by touching the power button. It would light up but quickly fade away. The cpu will not power up either way. I tried changing the power cord. I tried moving the computer to another room and using a different outlet, but nothing happens. Does anybody know what the problem could be?
