I realize most projects here already have pull-down resistors, but the article may give you insight into whatever might be causing the popping in your build. Plus, even if you have a pull-down resistor, you could have a bad solder connection on it. Folks reading your question have no clue as to what you have already considered, tested, tried, and ruled out as a possible cause. If you want more specific guidance you will likely need to provide those kinds of details about your build and the testing you have already done to get suggestions of other things you could check.
