my HP G60-125NR is not booting up.

Hey guys!

I need your help, my HP G60-125NR is not booting up. All week the laptop was working, has never failed before. Came back yesterday switched on the laptop, nothing appeared on the screen. There light on the power, there is orange light on the wireless button and there is light on the small keyboard button.

I have done a hard reset, still it does not boot up! the laptop is only 15 months old. I hope its not the motherboard.

thanks guy!
