I tried doing a repair to Windows XP. When it installed and I got into Windows, the themes were gone, I could still not connect to the Internet (part of a rapid chain-reaction of events before Windows croked), and when I restarted I could not even log on. It would get to my wallpaper and hang.
In my latest turn of events, the new Nvidia chipset drivers refuse to install properly. I uninstalled the old ones, restarted, then installed the freshly downloaded ones. That somehow affected the ATI drivers (I was going to update them anyway). Everytime I would open Forefox the dumb Nvidia firewall would kick in asking for Firefox's permission to connect. When I would click accept I would get the blue screen of death. I uninstalled the newest drivers and went back to the ones included on my motherboard's CD. I'm going to get rid of the Nvidia firewall and go back to Zone Alarm. I liked Zone Alarm.
Maybe it has something to do with the current revision being 6.66.
