can anyone explain why my computer shuts down when I am transfering files over to my xbox from my computer. I have been transfering files for months now with no problems and now it will get about 60-70 MB into the file and then my computer shuts down. I have two network cards, one for internet, one for network cable to xbox. I did just recently install Norton System Works, but I tried disabling it and then transfer with FlashXP and it still shut down. I am guessing it has something to do with Norton.
