Unplug from AC, open the case, clean if necessary, reseat the memory mods, use Electronic Contact Cleaner spray on contacts, plug in, push the on/off button. Does it begin to start, and in a few seconds completly shuts down? No LED's , no fans, nothing? Sounds like a PSU failure. Mine went out in 6 years.
