We have a DSL line that seems solid and when I test it seems liek the speeed is good. But recently when we try and watch video or even pictures it is skipping or all jumbly. We have an imac 8 and have updated all software running Mac OS X 10.5.8. Any thoughts I am not really computer savy so please explain your solution as simply as possible. Thanks for the help.

iMac, OS X 10.5.8

    How much free space is on the HD, where has all the space gone?

     

    OmniDiskSweeper is likely the easiest/best, and is now free...

    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.

     

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

     

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