Does it happens at specified times (example at midnight, or every
hourstrike).
If yes, it might be programs like updatedb, and some postgresql updaters,
which run automatically using crontab. Most of them involve 
"find / blah blah -exec foo", which mean they search all of your hard disk
bringing your system to a crawl. When i get too irritated by these, i do,

milkyway$ [my god, what's happening]
milkyway$ su
# top 			(to find the culprit process, the topmost process)
# killall -KILL find
# ^D
milkyway$

Of course, if you have important postgresql database, or are running
truely multiperson environment, you should not do such things,
but consider changing the crontab itself.

The files which run hourly are in /etc/cron.hourly,
similarly the daily files are in /etc/cron.daily.
