Need more information is the screen just "blue" or are you geting BSOD windows blue screen if so it should have messgage, can you get into the BIOS some laptopss (like HP laptops) have a diagnotic mode you can boot into to check the hard drive and memory. Also what the model of your laptop specs etc.
