Last year I swapped my motherboard and processor and all has been ok until today when I connected my Samsung Dv camera (model VP-D371W) up to the firewire port and it says it can't recognise it. I have been on the microsoft windows update site and downloaded any updates available but still the same problem happens. My operating system is XP SP2 and my old hard drive had windows movie maker on it (This is still installed on the second hard drive)my old system on my old hard drive was xp media center, but this is no longer in use, as when I changed the Motherboard, the hard drive needs the OEM code to work it and as it was pre installed I cannot obtain that code.I also have Corel ulead videostudio 11 installed, but neither windows movie maker or Ulead videostudio can detect it. It worked fine before I swapped m/board etc. Can anyone throw any light on how to fix this as I am at a loss with it now.
