Hi Anthony, Yes, I've tried the drivers but no dice. I downloaded the one set and they still gave the BSOD with the "Fatal Exception 06 ..." message. When I tried the older version sent by CL Tech support, it didn't BSOD, but it did hang the PC (the variety was nice, at least). I sent more detail in my response to the email from tech support. Thanks for the help - I'm running out of ideas here... I've disabled USB devices, turned off my anti-virus and firewall - I've never had a program do this before. I guess my timetable for a system upgrade is going to have to be moved up.... ;) If there's any more info you need, just yell! :) Bonzai Gopher
