I got Skyrim Legendary edition for pc a few weeks ago, and I enjoy it as hell with the posibility to mod it. Only one thing, approaching to 90hrs of gameplay Im starting to see purple textures mostly in armors and they come and they are ok after I reatart my lap, but then again maybe the next day I see them again. Any ideas why this happens?

It sounds like you are actually missing textures. Textures that are failing to load. A screenshot would be helpful.
