Ok, I just bought a use psp(9-22-05,$200, but no memory stick,v1.5) at EB and I just oppened it from the box and now its having some serious problems. Like when I charge the battery I have to take out the battery in order to keep it from "freezing" and shuting itself off. Then when I just "tap" the upleft, mid, and down-right section of the psp back section, it freezes then it turns itself off. Is there still a way to fix this problem and still keep the v1.5 psp. Someone please help I dont know what to do.
