Before spending the money for a new logic board try just one stick of the correct RAM. You said you got it "with these symptoms", and listed no symptoms. You have a power supply that you don't know if it works and a knock off battery that you don't know works. RAM that you don't know works and you want to replace the logic board? You have to many variables to isolate a problem. Please tell us the symptoms before and after you replaced the DC-IN board.
