The problem:
When I turn on the conputer, the fans on the CPU and power supply spin for one split second and turn off. I have replaced the MB thinking my refurbished was bad since the system light flickered. I then replaced the Power supply since I originally purchased a 400W. I have tested the processor and the processor is good in other machines. I have also placed in this new machine a 700W power supply from a known working machine with everything the exact same EXCEPT the motherboard and Graphic card which both are more planned for gaming. I have double checked all cables and even replaced the case thinking the front connectors were bad. The ethernet port does light up and blink when turned on but that is the only hint of life. I am stumped and do not know where to go from here. I have disconnected everything except the 24pin connector and the 8 pin ATX which are required by the MB. I have also disconnected everything to include the RAM and fans.I have even double checked the CPU mounting to ensure it is seated properly.
Any thoughts??
