When I open up the MC launcher, I login and then get to the title screen. Then everything freezes. MC proceeds to take up all my processor power and make my computer run really slow, I basically have to shut it down by ending the process in Task Manager.
I'm going to have to downgrade to 1.4.5 until this is resolved. It works flawlessly.

I held F3 + C for 2 minutes exactly.
No crash, I had to close it through Task Manager again.
Another thing, 1.4.5 and other versions have stopped working. I am beginning to think it might be a problem with my graphics card, since Minecraft and other OpenGL applications are strangely running very slow.
