Just a suggestion...
I would seriously consider deleting your hard drive partition and recreating a new one with an NFTS (or FAT32 if you must) format and install from scratch. The upgrade CD will allow you to do this. It will ask for an install CD of an older Windows version during setup.
Installing an upgrade over a previous operating system is risky. It is rarely done correctly and usually will display errors after install. Most individuals will purchase the upgrade when their previous operating system is having too many problems. Windows XP upgrade is only going to replace the files necessary in your old OS. Therefore, it would never know if there were problems or not with your older operating system files.
By the time you troubleshoot this problem and find a possible solution, you would have saved time by simply wiping the drive and starting from scratch. Then you are guarenteed to start with a fresh operating system with no known problems.
Let me know if you need help on how to completely wipe your system clean.
