[ubuntu] Ubuntu 9.10 Freezing (unresponsive keys, laggy or unresponsive mouse)

http://ubuntuforums.org – Im extremely uber nub when it comes to Ubuntu (first distro) and I'm having troubles with it freezing on me. I think it might be a hardware issue maybe something with overheating. It seems that it takes longer to freeze if I haven't used my laptop in a while as opposed to trying to reboot after a freeze, where it almost freezes instantly again. Any help would be great. ATI mobility Radeon x1400 is my graphics card. PS is there any hotkey to open up terminal? (Hardware)
