The main thing you are looking for now, is to identify the guilty process.

ps aux will show you something like this:

chady    24127  0.2  0.4  2264 1296 ?        S    14:23   0:02 blah
..

The last number before the binary name is the amount of CPU time this
process was using
So you are looking for processes that have a large number there

Until you identify the guilty process, we can't know what is going wrong.
