Both of these machines are Dell XPS 9100 Win 7 64bit. I hope the above info is helpfull. I personally think these BSOD's have to do with a Win 764 issue with the hardware addresses on this Dell hardware. I say this because I have Win XP SP3 32 installed on this machine also and have never had a BSOD!
