How can I talk to a girl when everyone else is talking to her!?

Hey, im a teenager (17) and this girl just moved to my school. After two weeks, im really startin to warm-up to her and like her and stuff, but every time time I hear about her being talked about, its some dude who's talkin about trying to go with her. Im kinda good looking, i guess, and I think we would work together, but how can I try to talk to her in a way to get her to interest in me when about every other guy knows her and wants to get with her too? sigh...
