defretman, did you check the answerbase and 'search the duc'? People have had this problem before, including me. For me, the problem was a firewire card that didn't groove with my motherboard. I has to switch my firewire card for one that was VIA chipset based since my motherboard is VIA chipset based. Might also be an IRQ problem. Search around and post again if you're stilling having problems.
