Well..I was half right about what I had read. I would go ahead and try this anyway since it deals specifically with auto opening of CD tray, and I will find another utility that stops start up programs selctively which is real easy to use and speeds up start up remarkebly.
May help...may not but good to have either way
"Reject Your CD's Auto Eject
The Annoyance: Windows XP mindlessly insisted on popping open the CD-RW drive every time I finished writing data to a CD--whether I wanted to eject the disc or not.
The Fix: I scotched this habit and saved my drive from extra wear and tear in just a few clicks. Open My Computer, right-click your CD-RW drive, click Properties, Recording, and uncheck Automatically eject the CD after writing.

here is the start up program fixer utility. I have installed it at home and it works great. May or may not have anything to do with your problem, but perhaps there is a program loading that is hidden of sorts..you will be able to find it, and stop it with this:
Your System Tray Runneth Over
Uninvited icons from AOL, Netscape, Real, Yahoo and other vendors take up screen space and gobble up resources when dumped in your system tray. Follow these steps to keep programs from scattering their icons on your desktop, Start menu, and system tray, and to remove them after they appear.
Watch the installation: Stay alert when installing software. Always go for the custom installation instead of giving the installer free rein, so you can choose where the program plants its icons. Note that the program will still be on the All Programs submenu of your Start menu regardless of your decision.
Protect your system tray: WinPatrol is a freebie that alerts you whenever a program attempts to add itself to your PC's Startup group or Registry. The utility guards every place where bad guys might want to stick a Trojan horse or automatic-dialing program, among other nasties. When WinPatrol detects a forced entry, you can allow the program into your Startup group if it's legit. If you say no, WinPatrol blocks subsequent attempts by that program to invade your Startup group.
