Melee Hitbox broken

[Askilo]

I just bought skyrim for pc, I played a bit first to make sure it installed correctly and even then i had two problems. One was the hitbox and another is misplaced shadows. The hitbox works fine with the bow and im pretty sure it works with magic (kinda hard to tell when you engulf your enemy in flames whether its always working or not.) When i first discovered the hitbox not working correctly i shrugged it off as lag and proceeded to play, but now its full on retarded standing right on top of the enemy wailing away but no damage is dealt (this still drains stamina). I do currently have 16 mod installed and active.

Current mods (in order):
Dawnguard DLC
Fallout 3 Hairs
Apachii Hair
Sky Ui
Life v1.1
Crazy Hairs
Race Menu Plugin
Race Menu
Amazing Followers Tweaks
Zt_Followers
Dual Sheath Redux
Immersive FP
Oriental Armor and Weapon
Saturation Boost
(i just realized i have a lot of hair mods)
I also have Sum and Boss
Please note that i tried the regular version first and the problem was there but not as bad as it is now.
