I have installed Ubuntu 12.04 64-bit on my Alienware M9750 laptop. After installing with the Alternate CD, the login screen comes up but I cannot type my password and within a few seconds the computer reboots. I had Ubuntu 11.10 64-bit installed prior and it worked fine. Could someone please assist me?
