I've been playing Skyrim for a good 3-4 months and I just encountered freezing in the game play, when I run/walk in the game it freezes slightly but it still works. And in the main menu it will work but it freezes for 3-4 seconds and continues, just like when I run/walk in the game. I was thinking maybe it was the mods I was installing, but I do it correctly using Nexus mod manager. I don't have lots of mods, maybe around 15-25 installed. But I just don't understand why it's doing this, on rare occasions it's freezes and the sound still plays. Making me quit the whole thing, can someone please help? I really need a solution to this, thanks guys!
Well 15-25 mods is definitely quite a few mods. Are any of them big graphics changing mods?
Also try these two things:
Verify Integrity Of Game Cache in Steam
Run as Administrator (fixes many problems for unexplained reasons for me..)
