Can I assume a new last name in Pa without having to go through the court process?

I wish to change my last name on all legal documents because my birth parents do not want to have anything to do with me, and I do not want to share a name with someone who doesn''t want to have anything to do with me. What do I need to do so that I can assume a new last name without going to court. How can I change my name on my social security card, and drivers license, also birth certificate? My biological mother was mentally abusive to me from a young age, and my biological father did not do anything to prevent her from being nasty to me.
