Hi, I guess I am having hardware problem with my FC5 box. The box suddenly hangs without any user intervention, displaying message something like (in console mode , no GUI). a) DWARF UNWINDER ...stucked at some point b) FATAL EXCEPTION on Interrupt This is not the first time it happened. During first time it happened, I thought it was a motherboard problem, so I exchanged the new motherboard to same kind. Exchanged everything except Harddrive and CPU. Now this problem suddenly popped out again. So here are my questions: =================== 1. Can CPU be defective?? Is it possible?? How and why? 2. If I change the hardware entirely (I guess I can't find the motherboard and CPU of same kind anymore), can I still use my old FC5 installation ?? What I mean is will my old FC will detect the hardware changes and make necessary adjustment with drivers and everything will be fine? I am afraid if I need to reinstall entire thing again, it will take considerable amount of time since it is heavily customized and need to interrupt the normal work. ============== Thanks
