I got the xbox in the middle of january 2013 with the skyrim game CODE no disk inside. I have both dawnguard and dragonborn.
I played it untill about 2 weeks ago my old level 33 dark elf vamp. lord account stoped working. Every single time i loaded a game, it would freeze about 3-4 minutes no matter where i was or what i was doing. I reset the game and system caches, deleted all of my saves exept for the last 5 or 6, turned off autosaves, and reasearched it. Turns out I had discarded too many items on the ground and they where clouding my games memory i think, so I started a new charactar.
It is currently a level 17 dark elf sneek mage. I had gone into whiterun to sell some stuff. I got into the general goods store and had sold things untill belathor(or whatever the salesmans name is) was out of cash. I saved, killed him, and reloaded my game so he would have his money back, and repeated that several times.

Than i tryed to leave the store. Normaly when you leave a store to go to a major city you get smoke and no item or tips in the loading screen. But this time a sword poped up along with a tip, and about 3 seconds later it froze.
This is a freeze where the whole xbox is frozen so I have to push the button on the xbox to turn it off

I tryed all of the things above in the first paragraph again, and also i tryed: disconecting and reconnecting the controler, loading a previous save in that store, going out the other door, putting my weapons away, waiting 20 minutes.
Finaly I loaded my save in WHITERUN, not his store, and i could go in and out of his store freely UNLESS I BOUGHT SOMTHING. Than it would just freeze again when intryed to leave the store.
Any advice is greatly appreciated.
I also sprayed my consol with canned air and nohing
Thanks so much

Bill
