I still have a number of Win 2000 workstations but I have done some upgrading to XP. For the most part I have had no problems until now. The system that is causing me a problem is a Dell Precision 450. The CD Drive worked fine before the upgrade but now has a yellow info tag on it in the hardware list. I have so far replaced the original drive and and cable. I uninstalled the drive and let windows search it out and I still get a driver error. This problem seems to be restricted to only this system as all the other upgrades were Dell systems as well. I'd like to find a solution to the problem without having to do a complete re-fit. I would very much appreciate some insight into this.
