Host Keeps Suspending for CPU Usage

My host has suspended me for going over 10% of the CPU’s usage twice now. Are there ways I can prevent this? Their customer support is terrible and referred me to the WordPress forums for help.
… if you have recommendations for better (cheap) hosting that would be appreciated, as well.

I already have W3 Total Cache installed and my website is http://www.silencenogood.net

Much appreciated!
