And referencing your issue with computer names do this
OK..on the Win 7 machine Right click computer, choose properties, in the frame called Computer name, domain, and workgroup settings, click "Change settings" click the change button in the result dialog box in the computer name box change it to something intuitive like Win7-PC and underneath that select the Workgroup radio and change that name to something also intuitive like WORKGROUP. On the XP machine do the same thing (Just Use A Different Computer Name, Like XP-PC and The Same Work Group Name Like WORKGROUP, you change this under the computer name tab on XP after right clicking on my computer
First, you're welcome. Second thank you for hanging in and not giving up. Third sorry to hear about the new problem, maybe try to go into device manager and uninstall it and reboot, it might work, can't hurt. Also if you want to zip and upload the blue screen .dmp file I can try to take a look at it to see if we can determine the cause.
