have you have other things running. if so. stop running things if you don't use them.
and mac is the only computer i hate. the others a good and ok.
oh and mystic. here is just some ideas of what to do.
1. open the cd drive and leave it (if there is a cd)
2. close programs you don't use like Skype etc.
3. if your room has high tempeture. put computer near a window.
4. clean computer. it will help the dusts get out because some of the dust just blocks the heat coming out. If you can open up your computer and clean. much better way.

Also is it a laptop desktop?
