Blackberry Tour won't startup

I have the Blackberry Tour 9630. It was working with no problems, maybe going a little slow, so I decided to do a quick pull, hoping that would fix the speed problem. Now the OS won't start back up. I've tried taking the battery out and putting it back in, but it'll being rebooting, but the loading bar will only fill up so far until it freezes and won't load. Not sure if there's anything that I can do
