There are a lot of reasons for your computer to generate a blue screen, every computer does even if you know that everything is ok I could read a dump file created by your system automatically when u receive a blue screen and tell you what is happening, but I can tell you that not many of the blue-screens that you receive could be fixed with something on system, your computer might have an Hardware issue. If something is wrong on the system itself, it could be fixed by uninstalling the program that leads to it/update the operating system and so on.
