why does keyboard ghosting occur?

keyboard ghosting on my keyboard stops for a while and then starts for a while

Great explanation here: Keyboard Ghosting Explained! If you are having ghosting issues the only definite way to completely eliminate it is to buy an anti-ghosting keyboard. 

 

There is another solution which you can try but isnt guaranteed to work, you have to go into your game settings and remap the control keys to various ones until you find a comfortable set that wont ghost. You can find some suggestions on which keys to remap here though bear in mind every keyboard is different: Which controls keys do you use?

Besides what @Ninja said above, I also use this link: https://scratch.mit.edu/projects/20966625/ . I have a ghosted keyboard too unfortunately, but I noticed according to that site that I can press 3 letters and an arrow key at the same time, but I couldn't do that with space bar. Now, it's way better. I must warn you tho, the first few days are going to seem really awkward and my hand actually hurt me a bit when I first did that. I got used to it and everything was back to normal a week later tho, and I'm glad it happened xD
