BB Curve :: 9300 Freezes Nonstop Every Few Minutes

I got my Curve 9330 in Oct 2010, it started freezing about 4 months ago, once every few weeks, over time it has gotten worse, so now it freezes every few minutes. Some freezes are "screen shots" where the time is off by a few minutes like its been frozen about 7 or 8 min and the cursor won't move, and some are freezes with the timer like its waiting on something. It takes me about 30 min to do something (text, email, facebook, anything) that should be a quick 2-3 min check. I have taken the battery out and that works for about an hour, then it goes back to freezing. I have done shift+alt+del to reset and that works for about an hour. I updated my OS, it stopped for about 3 or 4 days then started back up. I have checked to Application free space, there's 158.6MB. I do use my phone a lot, mostly quick check of things throughout the day.
