1. Works when SP2 is slipstreamed. 2. Yes, I update after I install. 3. I'm downloading the latest ATI drivers from the site each time after a new install. The drivers on my copy of XP work, yet the new ones don't, that's my problem. 4. Nope. To Crash&Burn: Yeah, I download them everytime from their site. Also to clarify, my copy of XP Pro slipstreamed with SP2 is compatible with the new drivers. It's when I trim the OS with nLite that they become uncompatible with each other. Guess I'll just use VMWare or create a new partition to go through each thing and see what's causing the problem.
