The MC version I am using is 1.8

After starting MC it freezes and then crashes. Even when not loading a map. After about 5 seconds regardless of what is on the screen it freezes and then crashes. Another issues is when starting MC the splash MC graphic is not rendering and is off center. Looks like an equalizer. It also load a few graphics over each other during start.  Loaded a game this morning and a few hours later now it won't open.
