could be the ram?
Try removing one stick of ram and re-running the installation. Also, i would open your pc up, and make sure all the parts and connectors are tightly secure...who knows; perhaps somethiing came lose while transporting. otherwise, i doubt its the motherboard, because if it was...chances are you wouldn't even be able to boot up without any error messages. That being said, do you get any error messages on POST???
