You need to look at the output of "ps ax" or "top" and see which process
is sucking up the resources. You then have to sort out why that's
happening.
If this is the first boot on the machine, the dread "updatedb" process
may be running. It can take a lot of resources. Either wait for it to
finish (it will, eventually) or kill it and let it run when your machine
isn't busy. It is what updates the "slocate" database and typically
runs at 4:00 a.m.--provided you leave the machine on. If you shut the
machine off and 4:00 a.m. rolls by while it's off, the process will
launch shortly after the machine boots so it can "catch up".
Of course, if you don't need the "slocate" command then disable the
updatedb process completely by editing /etc/updatedb.conf and changing
"DAILY_UPDATE=yes" to "DAILY_UPDATE=no" and killing any currently
running process.

I wouldn't worry about those. They're related to the ACPI (Advanced
Configuration and Power Interface) system and aren't critical. You may
wish to turn off ACPI ("chkconfig acpid off;service acpid stop") or
boot with "noacpi".
