Usually thats a symptom of bad ram, or bad motherboard, BUT its possible esp 
in laptops for a short in a peripheral to cause problems like that. However 
the fact that it puts up the splash screen says to me that its able to 
execute the bios entrypoint, so the processor is initializing and talking to 
the bios and the video subsystem. My experience is that at that point if you 
have NO useable RAM in your machine, then the system gets hung because it 
can't run POST. Desktop machines will beep at that point. Definitely try 
removing and reinserting RAM (if your machine makes it reasonably 
accessible). Sometimes DIMMS get loose or slightly corroded. You can clean 
the contacts on them with a pencil eraser and then replace them.
