Hi, I have been using Nero Ultra Suite for about a year now without any problems. I just rebuilt my computer with upgraded hard drives and applied Service Pack 2 for XP. I also went to Nero's website and downloaded the latest updates. However, whenever I start Nero Burning ROM (or any other app in the suite), my computer immediately reboots. My computer details are in my profile if that helps. I would greatly appreciate any and all help.
