Not Loading

So, I've been trying for 2 months but nothing works. i exported the game to test it, level_menu and level_00 both work but level_01 just does not want to load. My computer is slow, could it some how damage the files some how? When I open the level in the editor I can see the level but when I test it on both the unity editor and the exported builds, they don't work. Is there anything I could do? Oh and also, some textures did not load.
