I recently had the same problem and fought it for weeks thinking that it was something I had done during installation or messed up through downloading. I did repeated installs but always ended up with an unknown something taking up 100% of the CPU time. I, too, had a Pentium 4. I desperation, I pulled off every extra card and disconnected all but one hard drive. This wasn't the problem BUT, when I went to start putting stuff back, I noticed that the cooling fan was hanging loose (and this explained the messages I was getting about the CPU temperature being outside limits). I fixed it back on and crossed my fingers but the damage had been done. So I purchased a new CPU and everything is now AOK and running at full speed with no anomalous something taking up 100% of the CPU. It's an expensive trial if that's not the reason, but I was at my wits end and the expense turned out to be justified. Lesson learned : always make sure that the cooling fan is seated firmly home before powering up. CroombeFP -- This e-mail produced entirely under Linux.
