Skyrim crashing randomly or after loading

[ThisAintTheWay]

Hello. So, a few days ago, Skyrim was working all right. Yet now, it's suddenly crashing whenever I play it for one or two minutes and sometimes even at the loading screen. I've tried using LOOT and Tes5Edit to see if it was any mods I had, and while they did show some warnings, it was nothing serious, and I've already "fixed it". But it keeps crashing. Could someone help me?

 

My load order, if it helps:

1. I would suggest you use the Unofficial Skyrim Legendary Edition Patch. It fixes a lot of bugs and while some people like said bugs, it also plays nice with a lot of your mods. If you do get it, make sure you update each of your mods to reflect the usage of this. I know RS Children has a patch for USLEEP as a separate mod.
2. I would suggest to move your Random Alternate Start to the bottom of your load order. While not necessarily required like Alternate Start - LAL, it does work better there.
3. To fix your main problem, I would suggest trying first to simply defrag/restart your computer/steam client. See if that works. If not, try to delete your skyrim, update, dawnguard, hearthfires, dragonborn .esms from your skyrim/data folder, then revalidate your game cache through steam. Some people this has worked for. Make sure you reclean your master files after this with TES5Edit
