Oh dear, sounds like BSOD. Blue Screen of Death matey. If you don't know what you're doing best to take it to someone who does. My daughters bf had that once on his desktop pc and to be honest all i did was take the small battery out of the motherboard for a few seconds and then fireed it up and it was fine after that, whether or not it would work for your laptop though i wouldn't know but may be worth trying before you spend money on a professional to sort it out.
