Thread: Regular Kernal Panics - please help.

Hey, No issues running Leopard so far, it's failed to wake a few times but otherwise a good experience. That was until yesterday when my MacBook decided to repeatedly panic causing a transparent black box to appear with a power logo telling me to restart the computer .

There's also this post that I made before I had heard the term kernel panic http://discussions.apple.com/message.jspa?messageID=6018729#6018729 to summarize, no USB devices, occurred while working on an Excel file on a windows type server. Never had the problem with Tiger. Using a brand new MacBook Pro. In future I will save the crash report but I hadn't used these forums before Leopard and didn't think that some-one else could...
