    Hello, see how many of these you can answer...

     

    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

     

    http://support.apple.com/kb/PH7029

     

     

    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?

     

    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.

     

    Open Console in Utilities & see if there are any clues or repeating messages when this happens.

     

    In the Memory tab, are there a lot of Pageouts?
