AFTER SO LONG, THE GAME FINALLY WORKS!
My Skyrim was crashing about every 15 minutes. I could play for an hour if I was REALLY lucky.
My textures kept turning purple.
The game would just lock up and I would have to do a hard boot.
It usually just crashed to desktop for no apparent reason.
I tried everything. Changing the sound and graphics to a low setting. Visited dozens of sites with suggestions that didn't work.
Last night, I played for about 8 hours. I was actually trying to get it to crash. Nothing turned purple, the game didn't lock up and it never crashed. 8 hours! It was like a miracle.
This is what I did.
1.) I already had Large Address Aware --- but it wasn't working
2.) I already had the 4GB Skyrim Launcher --- that too wasn't working
3) Last night, I found a game-pro site that toold me to do this....
a) Open command prompt with Adminitrator rights. To do this, go to Programs, Accessories, right-click on Command Prompt and select "Run as Administrator."
bcdedit /set IncreaseUserVA 3072
and enter it at the MS-DOS prompt
c) restart the computer... and play Skyrim without crashing for the first time!
