I think I found a fix. It works for me anyways. 1.) Validate your files in Steam. (just to be sure) 2.) Exit completely out of Steam 3.) Open Windows Explorer, go to (your steam folder)\steamapps\common\skyrim 4.) Launch the game by opening TESV.exe I just played for 45 minutes, no crash whatsoever. I used to get the black screen of death after 5 minutes, like the dude who was nice enough to post the youtube video. I'm running a Radeon HD 6950, Windows 7 64-bit, with a AMD Phenom II X4 965 processor (3.4ghz) Try it out, and post here if it works for you.
