どうやってしますか versus どうすればいいですか


I have a difficulty to decide which one I have to use between どうやってしますか and
どうすればいいですか.

Is there any important thing to differentiate their usage?




Not an expert, but どうやってしますか sounds more along the lines of "How do you do
this?" while どうすればいいですか sounds more along the lines of "What should I do?"

Also, どうやってしますか sounds more informal than どうすればいいですか.

Would appreciate any corrections if I'm wrong though.
