I've had skyrim since it was releases in Nov,2011. I have hearthfire since that was released and do not have any mods. I have a total of 5 saves so I know there not the problem but today after playing for about 5hrs (12-31-12) skyrim has crashed as soon as I eather load a game or start a new game. I've restarted steam, my computer and verified the game cache and reinstalled the game with no improvement. Any advice on how to fix this issue would be appreciated.
