Help Samsung Galaxy s2(sph-d710) Boost, Will not turn on

I have a galaxy s2 that will not turn on. Started out only staying on while it was plugged in. now it will not turn on, either goes to the samsung screen the turns off or the boost screen. when I plug it in the battery charging icon shows up showing fully charged. Every once in a while it will boot up fully but when it does it freezes. I recently did a factory reset, would that be the cause?
I am willing to do whatever it takes I need my phone back...
any help is appreciated.
if you need more info let me know

also I have downloaded some one click restore but my computer will not recognize the phone....
