I have found my tv tuner card was failing and causing occasional lockups, one of which occurred during upgrade of the video driver. I also found my video card air intakes were clogged with dust so I cleaned them out as that may also have contributed to the problem. So with the tv tuner removed and video card cleaned out I have re-installed ubuntu and everything appears to be working.
