I wish the solution to my problem was as simple as remembering to put the memory in, but it isn't. The situation is this: the computer is seemingly in perfect working order, one evening it is shut down and the next morning it doesn't power back on. Pushing the power button gets no response whatsoever, no beeps, no lights, no whirring of fans or disk drives, nothing. My first thought was that it was the power supply, but there are a couple of things that make me question that. For one, there is a small green light on the back of the power supply which turns on when the power cord is plugged in, I assume this is an indicator light and that it would not turn on if the power supply was shot. Secondly, I was able to cause the power supply fan to spin by using a technique like the one described at the bottom of this page: http://www.duxcw.com/faq/ps/ps4.htm
. It has occurred to me that maybe its just the switch itself which is bad, but I don't have a multimeter and so don't know how to check that. At this point it seems likely that motherboard is dead, but again I'm not sure how to test it. Or maybe I'm totally wrong and some wise tech guru out there can point me in the right direction. Your ideas and suggestions would be most appreciated.
