AdWord Crashing Eclipse

After i added my adword ad banner to my xml file it causes my cpu usage to skyrocket to 90%+ and then im forced to close eclipse. Not sure if the reason my computer cant handle is because of my cpu or its a code problem, but anyways these are my cpu stats I have an intel(R) Core(TM)2 Quad CPU Q9300 @ 2.50GHz cpu
