Actually I JUST cleaned my computer 2 days ago. And before those 2 days I was only getting CTD's and never sleepy screens. But you're likely right that it's the GPU overheating. I really need an upgrade. I guess I should turn my Skyrim settings down. During the Winter I was running ENB's and HD textures and the whole 9 yards without a hitch but now that its Spring here in Southern Arizona we're already getting 90+ Farenheit temps outdoors.
The only ini tweak I made was for the deadly dragons/ASIS compatibility that was recommended on the mod webpage. CTD's just so happen to occur only on loading older saves. It's weird because it only happens on my saves where I DON'T have my skill trees reset by the new legendary system with the uncapper on. If anything it should happening vice versa.
I'm thinking I might just delete all the mods out of my data folder and start over on both the mod list and on the game itself even though I really wanna get my character to 81 for the first time.
