If you have not yet done so, unplug the system, remove the battery and hold the power button for 30 sec. Remove and reinstall both memory modules and the hard drive.
If that doesn't solve the problem, it is likely you have a bad cold solder joint somewhere on the mainboard - the system board will need replacement to solve the problem.
