How to access dead Macbook?

When I try to switch on my macbook it doesn't work, it just comes up with a folder icon with a question mark on it. Any ideas as to what this means? Has anyone had this problem?
My charger also hasn't been working properly and I don't know if that could have caused a problem or not.
I have loads of music and photos on my computer and I don't want to loose everything. HELP!
