TP is always freezing at boot-up/hard-resetting after a soft reset! HELP!

[vinnyt225]

ok it just happened again; soft reset it and it did a hard reset. pissin me off loll. like im scared to even bother reload my sms. i reload my contacts cuz its quick. i use pimbackup. and to restore my programs im probably gonna reinstall my .cabs. i used sprite backup when i had stock rom. do i have left over crap in the registry and stuff? cuz i flashed 2 roms and its always doing this. im nervous to soft reset cuz its gonna hard reset or freeze at bootup. should i clear storage after flashing? theres an option to also format the "NAND MEMORY." would that help?
