[ubuntu] Freezes after switching hard drive from another computer

view story

http://ubuntuforums.org – I had a computer go dead, but I had Ubuntu on it, and decided to install the hard drive in another computer. I also upgraded the system using -u dist upgrade after updating, so I'm probably using 12.10 beta. I now have a blue splash screen, if that verifies 12.10 The screen freezes. I saw someone with a similar problem on this thread:http://ubuntuforums.org/showthread.p...mputer+freezes And I've done sudo apt-get purge nvidia* sudo dpkg-reconfigure xserver-xorg without changing anything, so I went to sudo apt-get update sudo apt-get purge nvidia-* sudo apt-get install nvidia-curr (Hardware)
