Why is my macbook pro running slow and I can also hear the fan running continuously

My macbook pro started running slow last night. I turned it off and waited til this morning to turn it on again. It is still running really slow when I browse through my dock or apps and everything takes forever to open, my fan is also running pretty loud, I could not hear it running until last night. Can anyone help me out?

MacBook Pro, Mac OS X (10.6)

I do not know your situation but I found this when I searched help in finder and typed slow and fan runs:



If graphics-intensive tasks slow down your computer

If your portable computer is slower than expected when you perform graphics-intensive tasks, such as playing games or editing video, open Energy Saver preferences. Depending on your computer, you may see options that let you improve graphics performance in exchange for shorter battery life.

  1. Choose Apple menu > System Preferences, and then click Energy Saver.

    Open Energy Saver preferences

  2. Do one of the following:
    • If you see Graphics options, select Higher Performance.

      You need to log out and then log in again for the change to take effect.

    • If you see the “Automatic graphic switching” option, deselect it.

      Your computer will always use high-performance graphics.
