Your error message, "Kernel panic - not syncing: Fatal exception" is too
generic to give any clue. Do you see other error messages in your log ?
Did you run any hardware test (with Dell you have such utilities on DVD,
I think they exist also on HP), to see if some hardware is failing, for
example RAM ?
