Skyrim freezes one second (as if loading)
Need help, Skyrim used to run really good before.. and while FPS wise (60fps) it still does, I seem to have loading freezes. It's during gameplay when walking around, I will hear my HD disk go crazy for a sec - game freezes for a second or so and then lets me continue playing. I was having this issue without mods enabled. By lowering graphics settings it seems somewhat better but it still freezes (just a bit less, I think). But since my FPS is high I don't see any need to lower the graphics.
It's obviously everytime when it needs to load something, so my question is how to fix this? I should probably look at disk defragmenter .. but incase that doesn't help, does anyone have other ideas for me? Granted, my Windows is sometimes running a bit slow (starting up, loading programs) and my HD drive is loading things all the time, yes I know.. background programs.. but I have none running other then Steam & AVG Antivirus (could this be an issue?). But other then that my PC has pretty decent specs, I might consider reinstalling Windows but that's such a hassle that I rather not to.
Is there anything aside from Disk Defragmenter in Windows to improve my gameplay/HD usage/loading in Skyrim? Load times itself I don't care, but while playing and having 1sec freezes every few minutes sucks.
