I want to install Lubuntu on a Pentium IV Desktop with 1GB RAM and I am currently trying it on Live-mode from a pendrive, just to be sure this won't give me trouble after proper installation to HDD, why is CPU usage permanently at 100% in task manager, even when in idle state? The system is not running slowly, so I don't understand why is this happening.
