ASIO Time Overload

Hello Everyone. Right now I’m running Cubase LE 5 on my Macbook Pro. The problem is that the There is an ASIO time overload indicator on my transport bar that is going off, and I’m not sure how to fix it so that so there isn’t an overload. I’m thinking that the problem just may be insufficient hardware. This happens regardless of whether I’m using the built in audio or my interace for sound output. What do you guys think?
