100% cpu use 100% of the time


Hi all, I'm using Mandriva 2006 and installed it great, except from the graphical drivers, but that's another story. I started linux one day, and found it a little slower than usual, I opened Gnome system monitor and found out that the cpu was used at 100% all the time. I quit kopete, kde wallet, amarok, and even the network monitor, but there was no difference. I know I haven't foud any process that was taking more than 2% of the cpu, but I also admit that I don't know anything else than gnome system monitor to see the cpu usage and the running processes.
The cpu in question is an AMD sempron 3000+ and it has 512 MB of ram at its disposition.
Thanks in advance for any help.

Hey Buddy, type "top" in shell and send us the output. top is an interactive command that shows the current running tasks ordered by cpu usage (by default) - very useful

If I understand right, it's LISA that takes the cpu. That's just about great, the LAN server... If I kill it, does it do anything to the Samba file sharing? Are they interlinked?

if you kill lisa, nothing will happen to samba...
