need help , dont know what to do

Can someone tell me what caused this and how to overcome it?

Does it happen with no mods installed? When does it happen? When the game loads or at some other time? If it happens without any mods try verifying your files from Steam. If the vanilla game is fine, uninstall all your mods then starting with the utility mods like Engine Fixes and SKSE try installing a few at a time until you localize the problem.
