Samsung Epic 4G :: Force Closes - Phone Freaks Out And Shuts The Screen Off

Everytime i reboot my phone, I get bunch of problems with my phone. when I try to open the phone dialer I get a force close on com.google.process.acore. Sometimes it completely prevents me from using the phone.

Then on occasion the phone freaks out and shuts the screen off, but leaves the navigation lights on the bottom of the phone. At that point the phone is completely unusable for about 1-2minutes. Sometimes when it comes back on, it starts rerunning the media scanner.
