Verizon 6800 keeps freezing

[whopper68]

So ive had this bad boy for about, a month, not the original its actually the second refurbushed ive gotten because my original phone no longer had vib function scroll wheel no longer worked

first replacement:
USB port broke

second replacement:
keeps freezing out, by that i mean ill be typing a txt, half way itll stop typing and just not work...
ill be running 1 app wether it be internet or sms , and itll freeze.

at first i figured hmm might be the 3rd party app i used to restore contacts (bitpim) the refurbished phone has 6.1 WM, my original phone was pre 6.1 so i figured f it ill just hard reset the phone once more and manual re input numbers as people call

nope, even without activating the bitpim my phone still keeps freezin. and its gotten worst

if the phone freezes and i soft reset itll do either of the following
freeze on the first image
freeze during the Verizon intro
freeve during the WM 6.1 page
Freeze right after it finishes loading
not even turn on at all

i just dont know what to do

so far ive done the following

hard reset 2 within a week - seoncd time without 3rd party app and still it does it

soft reset hundreds of times now...

any help would be appreciated, please
