Slow scripts in vanilla skyrim

[thaukor]

So, i've playing skyrim for a while, used to play in a notebook and i had a small amount of lag in scripts, but now i'm playing on a better pc, almost at 40fps and i have a really big amount of lag, if i run too fast zones won't load when i reach them, even npc's and objects won't appear, so, i can wait, but spells take a lot of time to work, bows fires arrows like 3-10 seconds later and npc's take at least 3 seconds to react after i attack them.

I have an APU A10 7860K, 8gb ram, and i don't think is a problem of my cpu, 'cause i used to play in a celeron idk what U with 4gb ram and with almost 70 mods, some heavy scripted, and now i'm playing only with skytweak (with skyre it was unplayable, some spells took 50 secs to be ready to use)

 

here is a list of the plugins

no dirty plugins and already cleaned all with tes5edit

what can i do? i really like skyrim t-t, so i don't want to stop playing it
