If you got the blue screen of death, then you might have to take your computer in to be fixed. This happened to me on my XP computer a couple of years ago, and my dad and I had to take it in to Best Buy, and they had to wipe out my memory (yes, literally everything on my hard drive) and start my computer over like it was new, except they only replaced the busted part. You might not have to do this, but I'm not tech-savvy enough to know what you should do. Just something for you to keep in mind.
