I'm about to destroy my computer, please help.

I have no midi tracks selected but when I play my keyboard controller I hear basic drum sounds in the higher octaves. I HATE BASIC DRUM SOUNDS! I can't handle this and need some help... pleeeeeease.

EDIT: shoot me in the head, sibelius was open. I'll let a few people read how stupid I am before I delete this post. Just down vote so I know that you recognize my failure.
