Did you hear the fans inside the laptop? My suggestion is to try external monitor to check out your screen is good.

Did you hear any beeps?

Try this 1,

switch off the laptop
Remove the RAM from the slot and switch on the laptop did you hear any beeps now?
If yes then switch off the laptop and reseat the RAM again properly, If you have two RAM's test it by one by one. If no beeps at all without presence of RAM your motherboard is faulty.

N.B There may be problem that lies between RAM or Graphic in certain case may be motherboard also.
