"I too have had random lockups for the last few weeks, which has been 
rather frustrating. The lockups can happen from within minutes of 
booting to within a couple of hours, but usually no longer than that. My 
PC runs fine under Windows and has been working fine for a couple of 
months since installing Lucid so I am pretty sure it is not hardware."
