More info needed. You stated that it started and then sputtered and then died. Right now does it power on? If it powers on does anything show on the monitor, if so what do you see? If nothing shows on monitor does the power LED on the computer blink a code or does it have any beep code? If nothing on the display but its powered on, does it power on for a bit and then shut itself down after a short period of time? Was this computer stored in a dry place away from humidity and weather?
