I got the game this morning, and it has been working fine. But after 15-20 minutes of playing it just randomly cuts out. I've got a 64-bit operating system, and 6.00GB of RAM (5.68GB usable)

Does anyone know if my SimCity will work on my laptop, I don't know much about computers as I usually play Xbox, my laptop has something like 2.40GHz what ever that is, and I've heard I need a minimum of 2.00GHz, will my game lag out or be okay? I've got 500GB of storage left on my laptop and I don't know if it will affect the game, if it does I have 1TB external hard drive, someone please help me. Thanks, Weza
