Okay, sometimes (quite often rather) when I am playing the game will randomly close. Not really a CTD, but it just exits. I don't know if it is a problem with a mod or something, I'm not sure. I have a lot of mods, they are compatible according to the descriptions for them. I use BOSS to do the load order so that shouldn't be an issue either, I am on a 64 bit system with 8GB of RAM, an AMD Radeon HD 6850, an AMD Phenom II x6 1090t, and the game is on an SSD. I have 0 FPS issues at all, even with the game on ultra settings and the mods I have installed on it. These are the mods I am currently using:
Dawnguard

HearthFires

Dragonborn

Climates of Tamriel / Sounds / Dragonborn - Dawnguard Patches

SPIKE

Unofficial Skyrim / Dawnguard / Hearthfire / Dragonborn Patches

Static Mesh Improvement with the Dragonborn fix and the Furniture Chest Snow Fix

Skyrim Flora Overhaul

Character Creation Overhaul / Oblivion Carry Weights / Dynamic Skill Progression / Diverse Races and Genders

SkyUI

Bandolier Bags and Pouches

Skyrim Redone Main / Combat / EnemyAI / EnemyScaling / Standing Stones / Perk Tomes / Races

SkyTEST Realistic Animals & Predators

Enhanced Blood Textures with Dawnguard / Dragonborn patches

Realistic Lighting Overhaul

Apocalypse Spell Package

Dual Wield Parrying

Alternate Start - Live Another Life

Purewaters / Dawnguard / Dragonborn

ReProccer

Immersive Armors

Improved NPC Clothing / Expansion

Skyrim Community Uncapper

Ruins Clutter Improved

Skyrim HD 2K Textures LITE

Realistic Smoke and Embers

Any help on figuring out why this is happening would be greatly appreciated as it has become quite an annoyance and I have yet to find anything online to help in fixing it.

Does BOSS recognize all of your mods? Check the BOSS log to be sure. Unrecognized mods are placed at the bottom of your load order and must be manually placed where they belong.

Also, you should probably be using a merged or bashed patch.

And, clean your dlc/mods with TES5Edit!
