Bobbin thread getting jammed

Question

I am trying to thread my machine. i successfully threaded the bobbin, but when i put the bobbin in my machine to thread it in with the needle to start sewing, the thread keeps getting jammed and wrapped around everything down in the bobbin holder area. (I'm not a pro sewer) I kept trying and then started all over with a new bobbin. Still was doing it. I know how to place the bobbin in the holder and thread the needle and everything, but my machine keeps getting a jammed up.
