I have a dual 1.25 FireWire 800 Power Mac that has been acting up lately. It was dormant for a couple weeks between Christmas and now, and when I went to boot it up, only the power button light came on. It is sending power through the ADC port, as I can get the Cinema display to turn on, but it too only displays the power light. I tried opening it up this morning, and hit the power button. It boots right up as normal, but if I try to close the case, it shuts off immediately. It works fine right up until the bottom case hits the top, or, if I close it really slowly, it works right up until I latch it. I've checked all the power connections I can find, they seem snug. So, my question is this: What the hell?
In summary:
-Power lights on both ADC monitor ans tower work
-boots fine, unless case is shut
-power connectors seem snug
