Hi and Thank You in advance for such a great site. I recently bought a new computer and gave my husband my gateway. Vista 32 - Never had a problem with it untill yesterday. When you boot up it defaults to media center and won't let you close it. If you do, it opens again. It has total control of the computer unless I start it in safe mode. I disabled what I could, but the problem still exist. Does anyone have any idea what's causing this.
