Thank you for replying Ctrl-X, I have a DFI LanParty Ultra-D motherboard, so they are all connected to the NVidia controller. I've decided to just start over, from scratch, and try adding things one at a time (regtweaks, RunOnceEX, etc.) to see who the culprit is. It will take time, especially since I no longer trust my VMWare results to be accurate in a real world situation. That's the beauty of three hard drives, right? I can use my third drive to format and install XP as many times as it takes. I started with a basic unattended including SP2, then removed a bunch of clutter and added SATA/RAID drivers. That was a success. Today, I plan on adding my regtweaks. Cross your fingers. Thanks again and if you have any ideas or tips, let me know. I'm always looking to improve my install.
