Skyrim graphics problem?
I started playing skyrim again today after a break from it, and these green triangle things (I can't really find another way of describing them) appear whenever I'm outside, I've tried uninstalling and reinstalling it, but it hasn't made a difference, I've even tried downloading it again. It was fine before but since starting again there's been a problem. Any help would be much appreciated! I've updated it to the most recent version too. There are some screenshots here:

(the first 5)

Also, the data files button can't be pressed on the launcher any ideas with this too?

Thanks in advance!

Also, I experienced a similar problem playing mass effect recently, this hasn't happened on previous playthroughs, just this one
