You might try disconnecting all periphrials, extra internal hard drives that you may have added and remove any non apple memory cards. See if you still have the same problem.

Slow process. :) By the way, I assume you have at least your data files backed up in case at some point the computer becomes inoperable in the extreme. Jens Jens Selvig ...Lost in Montana...
