One of my clients has a Dell PowerEdge 840 that worked yesterday but does not today. When it is plugged in, the fan starts up on high and it starts to boot even without pressing the power button. It has the normal blue light on the front but also has the no memory modules detected diagnostic code on the front. I have adjusted the memory, rearranged the DIMMS, and taken some of them out but still nothing. Also, I have taken all the components off of the motherboard except for the processor, but it still does the same thing. Further, I set the jumper to clear the NVRAM but still nothing. Any more ideas?
