Slow D2

[droid doctor]

In the last week my Droid 2 which is rooted with ZS 1.71 has been running slow. Every time I wanna pick a ringtone it gives an option to use the android system or the go sms pro app ringtone chooser to pick. Every time without fail my phone reboots. I've also noticed the reboots are longer than usual.
Any help or suggestions would be appreciated.
