A problem with my laptop

I have a problem with a Dell Inspiron 1546 Its problem Is When it turns on for some reason the screen does not turn at all, the LED does turn on and the fan spins for a second then it immediately stops,the LED stays a few seconds after the fan and it turns off as well But I noticed something during the fan's on n' off The CPU got realy hot also the 3 chips nearby which I think it's a video card also gets hot

What is the problem. I can't figure it out
