Did you install any mods?
Are you upgraded to the newest version?
Are you trying to load an old version instead of using the newer loader?

Update your processor, drivers, and graphics card. I had the same problem as you. If you don't know how to do it there are tons of tutorials of it on YouTube and the internet, if one says to download something, don't do it, you can update it from your PC with a internet connection. The only reason im not going to tell you how to do it is because every pc has different steps, windows 8, windows 7, windows vista, ETC.
