If some one... ANYONE could help that would be fantastic!
I've played skyrim for a while now (a few years) and I've never had this problem.
I'm level 45 (on my new account) and now every quest I try to complete my game glitches in some way, shape, or form.
"The Mind of Madness"- games freezes in the first corridor and I have to turn of my xbox and restart
"Dampened Spirits"- Maven Black-Briar is glitched into the river that goes through Riften
"Whispers in the Dark"- when I'm in the night mothers coffin Cicero stops talking right after he comes in and doesn't talk again
"The Forsworn Conspiracy"-it freezes right after the guard tells you your going to jail

have you tried clearing the game cache before the game loads.
