When I push the power button - power LED lights, fan runs, no beeps, no boot, no display, etc.. To turn off the power suppley, have to hold the button in for 6 seconds or it won't turn off. After I turn it off this way, wait 30 seconds or so, then push power button, boots normal without noted problems. If I wait too long after first attempt (5 minutes or longer), same scenario as the initial attempt. I've already tried a new power supply, replaced the on board battery with a new one, and reseated the processor and all cards - same symptoms. There are dip switches but I don't have the manual to see what the settings for these are and what changing them would do. Any ideas? Thanks!
