Ok... Here is the situation. I have ran into this a total of 2 times and still unable to pin point the exact reason for this problem. It is believed to be the PSU causing the problem.
The symptoms were the same in both of these past cases. When the whole rig would be unplugged from a power source for a prolonged period of time (1-2 days or more) they refuse to allow the whole system power. You could plug the power cord into the PSU and see the green LED light up ackowledging power being on. When you attempt to start the system by pressing the power button the fans inside (Case and CPU) all get a small jolt of power, enough to make them spin for a fraction of a second. The little green LED on the power supply then turns off. The only way to get that small jolt again is to unplugged the cord from the PSU and wait til you hear the high pitched sound of the PSU discharging the last bit of electricty. Then you can plug in the cord again and repeat the small jolt.
One system I was able to un-plug and replug the cord back into the PSU and keep trying to turn it on until eventually it gave in and started. This last time it didnt want to do even want to do that either. The only way to fix this last rig was to allow it to sit there plugged into power with the green LED on for about 1 hour... then it powered up, and runs fine.
This is one of the problems that I would like to figure out so that if I run across it in the future I at least know whats causing it in paticular and can possibly fix it provided its fixable.
