Anything I can do?

Was trying to format a CF card in a PCMCIA adapter [that read on my 3400; it's not Cardbus].  First time I inserted it, the machine either froze or restarted.  When it restarted, there were white and colored bars across the screen.  I shut it off and booted it normally.  When I inserted the PC card again the machine froze.  Then I ejected the card and restarted.  The bars popped up again and it promptly restarted to the Sad Mac - and chimes of death.
