I am trying to install 12.04 AMD64 Destop on a fresh hardware (Ga-A75N-USB3, A8-3870K, Samsung SSD, install from USB-stick. The installation shows "ubuntu" and some dots below. The mouse pointer disappears and comes back after a minute. Then the PC hangs at this point.

I installed the alternate AMD64. OK so far but how to update to a full installation? How can I find out what make my PC hang ? Many regards
