I have a pismo 400 MHZ. It will start up run for different amounts of time then it completely freezes. Sometimes it will freeze when restarting or run for an even shorter time then freeze. Is it the processor or the logic board? Can you tell from this description? Also it seems runs fine with all extensions turned off. When I turn them back on it freezes. I have gone thru systematically turning them on and off to see if a particular extension is the problem to no avail.
Thanks for any help.
