My 2008 Mac Pro with OSX 10.6.8 Model 3.1 just started to 'hang" for about 40 secs. periodically while browsing any website. Problem occurs with both Safari 5.7.1 and with Firefox. Internal temps appear to be OK. You can browse OK for a few seconds or so then it will hang again, then will be OK for a few seconds then will hang again. I haven't added or removed anything at all for several days. Tried restarting computer and doing an SMC reset with no help.

Anybody have any ideas?


Thanks for any help,

    If instaled, try temporarily disabling anti virus software.


    If you don't have a/v software installed, try a different DNS server.


    Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.


    Click +


    Enter these addresses exactly as you see them here.



    Click +



    Then click OK.

    Try a browser.
