How to stop services from loading?

Hi all,
I am new to this great software.

My Fedora 6 seems to run slower than before. It used to run quite fast when I had first installed it. After doing so much of 'Yum' etc. I am not sure if there are unwanted services running in the background. Right now it seems to stick as I move my mouse around and things takes time to open. Hope you understand. Just like in a windows enviorment.
I would like to know how do i stop unwanted services from loading in Fedora 6, I am sure after i find out what stuff i do not want i can stop them from loading and hence get a faster pc.

Please let me know the hard way, I mean in the GUi, it will be easy, but i would like the command line way, this way I would learn faster.
Thanks guys.

Code:

system-config-services

service Service_Name stop/start/restart/status

chkconfig Service_Name on/off

chkconfig --list

Code:

ps -ef

kill -sig process_id

Code:

man cmd_name

The init process

Thanks man, that was good
