After 5-10 hard restarts the lights for num lock, caps lock and scroll lock flash and the system starts. I guess it's the motherboard failure. That is all I get. Any suggestions?

I see the fans starting up (the laptop is still opened up), I see the lights on the front of the laptop, and the disc drive, blink. his comment is here Means they must be connected to the laptop and the laptop must be ON then you can actually use your multi-meter to measure the voltages.
