My computer is making a whistling sound for roughly half a minute after I shutdown the computer. Any idea what this could be? . I've also had what I believe(And what several have said) to be a malfunctioning fan for a fair while. Said fan occasionally rattles.
I'm currently scratching my head on how to design plains. What do I even put in plains? Some trees (but not too many or it turns into a forest)? Grass? A few bushes? That's a bit dull.
I'm looking for tutorials but Google didn't seem to find much (or maybe I have the wrong keywords). I don't know how to map plains and I don't know how to learn.
