Crash for no reason

I have a great computer but this happens

Game ended with bad state (exit code -1073741819)
Ignoring visibility rule and showing launcher due to a game crash
Deleting C:\Users\Hayden\AppData\Roaming\.minecraft\versions\1.6.2\1.6.2-natives-1045342994455125
Couldn't delete C:\Users\Hayden\AppData\Roaming\.minecraft\versions\1.6.2\1.6.2-natives-1045342994455125 - scheduling for deletion upon exit

What the hell?
