Hey so, i've been playing Skyrim for quite a long time, and these last months it's been horrible, because when i choose a save to play ( No, i don't have a hundred of them), the loading screens takes at LEAST 6 mins before loading the game, which is highly annoying. Any fast travelling also takes a long time, basicly, i spend more time watcing the screen load than playing.
I do not know what's causing this, i've tried lowering the graphics but it didn't work, i tried a sound fix, didn't work, and i'm getting a bit desperate here, i'd love any help.
I don't have lots of mods, and i don't think any of them are causing trouble, since i took them all off and the loading screens were still incredibly slow.
Here's some info on my pc:

Toshiba QOSMIO x770- 11Z
Intel? Core? i7-2670QM
CPU 2.20Hz
RAM:8,00 GB
64bits
DirectX 11

Please help me if you can.

My loading times are increase a lot if I use a lot of AA, hence I never use more than 4x.

I'd follow your advice, if i knew what an AA is...i'm sorry , can you please tell me what an AA is? I'm a newbie when it comes to computer language
