What I expected to happen was...:
The game should have started

What actually happened was...:
When starting a new world (or trying to play a saved world), the game starts with the player in a blue abyss with clouds. There's no environment at all (hills, trees, animals, grounds, nothing). Just blue with clouds like your flying in the sky. About 4 seconds later minecraft crashes and the loader window (the one you push play on to go into minecraft) is up and it has a bunch of stuff such as fatal error, I think it said bad ending or something like that. I'm resetting my computer so I have no screens shots.

Steps to Reproduce:
1. Click minecraft icon on desktop
2. Wait for loader window to come up
3. Push play
4. When minecraft comes up, press single player
5. Click start new world or click to play existing world
6. Error happens

Minecraft was purchased last week. Had a newer Toshiba laptop. Everything worked great. I accidentally broke the cometer by dropping it. I went out yesterday morning and got a new HP Envy (see specs listed). Downloaded and played minecraft for hours, no issues. I come home to play today and it seemed like it down loaded the new update when I went to start it. Then it started crashing (see above steps). I uninstalled and re installed the game several times with no luck. Updated java, no luck. It HAS to be the game/update. I'm not sure what else to do. I played it fine yesterday and today, crashes.
