Help! Phone going crazy

Today, my droid x is acting possessed. It keeps trying to bring up google search and voice search and cycles between them without giving me a chance to cancel it or anything. Paying the home screen briefly brings up the home screen, but then the voice search pops up again. It says audio problem. Lookout says everything is ok. The only way I am able to make it work is to attach it to my docking station. Am running 2.2 and have been for a week or so with no problems.
