Out of the blue I keep getting a kernel panic (You must restart computer) while using my G4. All I use it for is word processing and internet browsing. Seems to happen when switching between windows. Any suggestions on how to resolve this?

 

Thanks!!!

    If you have not done so already, try resetting PRAM

     

    http://support.apple.com/kb/ht1379

     

    amd resetting the PMU (power management)

     

    http://support.apple.com/kb/HT1939

     

    When you plug it back in to power, if you have been connecting the power cord to an old or overcrowded power strip (surge suppressor), try connecting it directly to a wall outlet (as a test to see if it makes any difference).

     

    As additional trouble-shooting, you can try starting up from a different startup disk, if possible.  This will help rule out a problem with your current Mac OS X installation.  If you don't have a different bootable system, you can try starting up from a Mac OS X installation disk in the optical drive.  If the problem still recurs while starting up from another system, the problem is more likely to be related to a hardware problem (and you can focus additional trouble-shooting in that area).
