I have been playing Skyrim on medium settings for a while now, with no problems. I think i have about 25 hours in. Suddenly, as I was finishing up the Thieves guild storyline, It froze for about 3 seconds, and then crashed to desktop. no warning, no explanation. I had not changed any settings or anything. Now when I start the game, I cannot play for more than 30 seconds before it crashes again. I have tried all of the fixes I could find online, such as lowering the settings, un-install and re-install, verify game cache, and other things. This is severely annoying. i have put a lot of time and effort into this character, and I would really like to play. ANY help would be GREATLY appreciated!
