I recently installed 2 GB more into my laptop however when i press the power button nothing happens. I dont believe the problem is the new RAM because if i take out my old ones and install the new ones in the same spot it works, however if i plug in both of them it does not work. I have an Toshiba Saellite U305-S2804. Please help
