I have had my Macbook for a few years and all still works well, but I also have windows on my computer as well.  I would like to reboot my mac start over and re-install all the files that I have on it now.  The fan on my Mac runs a little more often than it should.  My guess is that there is just a build up of stuff that can be deleted.  As a PC user I found that each year I had to re-boot my Dell to keep it running well.  I am assuming that Mac is similar only I don't have to do it as often.  Can someone please explain how I reboot my Mac?

    Install or Reinstall Snow Leopard from Scratch

     

    If possible backup your files to an external drive or second internal drive.

     

    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.

     

    If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.

     

    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.

     

    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

     

    4. Quit DU and return to the installer. Install Snow Leopard.

     

    5. Download and install the Mac OS X 10.6.8 Update Combo v1.1 updater.

     

    6. Reinstall your third-party applications and restore you data.

    The build up of stuff might just be dust. You can try cleaning it by cautiously vacuuming the exhaust port - use a soft brush attachment. Do not blow dust back into the MacBook.

     

    The following are some troubleshooting steps you can take to determine if you have installed software that is burdening your computer. Do not succumb to installing some utility or tool advertised to perform some magical incantation that will make it run like new. In nearly every case they will do the exact opposite. If you already did this you found the problem.
