Chirping Sound when running MS Office in MacBook Pro

I have a MacBook Pro and just recently, I installed OS X Lion on my device and it worked fine. Few days ago, while I am trying to run Microsoft office, I can hear a chirping sound that is produced by my device and eventually it will just crash. I forced close the program and then after a reboot, it works okay again. After that event, I removed Microsoft Office and re-installed it thinking that I will not be encountering the same issue again but I was wrong. Now I want to know if the issue is with Microsoft Office or if it’s not incompatible with my device? Or the problem is with Apple? I want to use the Genius Bar but I’m not sure if this can help. Finals is almost coming and it would be a great relief if someone can help me because I will be using Microsoft Word to finish my term papers. Thank you!
