Why won't it work?

I've had my Droid X for about a year or so now and just last week, it just stopped working. It will turn on but that's just about it. It will go to the Droid screen and then just freeze. I hooked it up to my computer and it said it was on safe mode. I looked up what this meant and how to disable it, but I can't do this because the phone won't fully turn on. How should I fix this problem?
