Resume Writing

Well, I was cruising around the internet earlier today and found this internship that I want to apply for. The only downside is that like every internship that I've run across, they want a resume. So I pulled up my resume on the computer. I was reading over it and it's a bit out of date but more importantly the thing kinda sucks, in my opinion.

So I was wondering if anyone has any tips that have helped their resume look good, or know of any websites that you've found to be helpful. My school has a department where they will help you with your resume, but I was hoping to get the thing done by the end of the weekend.
