If you still want some help, my advice would go with proper .ini tweaking and cleaning up your mods. Consider removing the mods that make no real difference to gameplay, such as: MoreRainWindy33percentLessView.esp - Don't really know why this is needed All sound .esp mods - Sound mods are known to be very heavy memory wise. better_torches_brighter_torchlight.esp and BrighterTorchesBiggerMagelight.esp - Sure these are supposed to be used simultaneously? Auto Unequip Ammo.esp - Sure it's a timesaver, but is it really needed? If you have problems running your game, removing script mods that don't have huge impact on gameplay should be cut out. Dead Body Collision.esp - Known to be causing problems with NPC AI getting stuck on the bodies. Immersive .esps - Having them all separated, thought about the merged version? People Have Torches.esp - For me, NPCs are using torches without this. Footprints.esp - Needed for gameplay? Headtracking.esp - This made some changes to NPCs headtracking? Needed? Spells Cast Light.esp - Needed? My stability improved greatly after installing SKSE v1.7.0 with the memory patch tweaks and ENBoost. Keeping the mods updated and clean helps a lot. I can't highlight enough how big difference can you make with good .ini tweaks. However tweaking them too much, or doing bad tweaks causes even more problems than you have now. I also noticed that your PC isn't that powerful and you use W7 Ultimate. I personally would recommend you to use a lighter version of Windows 7, as Home Premium is the best choice for gamers that have 8Gb RAM or under. Over 8GB needs Professional. Certain unneeded features can be turned off from Ultimate by tweaking your Windows 7 properly. Upgrading your hardware would help, especially RAM is cheap and easy to apply.
