Milli: service pack3 for XP? there are documented compatibility issues with sp3 and symantec/norton AV, my suggestion for that is the same for everyone running norton, uninstall it, and get something different and not as heavy on the system. (sorry norton fans, it's the root of many problems that I see day to day). My official recommendation is ESET, (small foot print in memory and disc space, negligable impact on the system resources, fastest and most accurate scan, highest capture rate of new and unknown virus/malware).
There's also some video driver compatibility issues (Intel video cards for one). Can you let me know what video card you have in your system? Easiest way to find out, right click on my computer, goto properties, then to the device manager tab, scroll down the list to video adapters (maybe called display adapters) and the name and model should be there.
Jammy: hit it on the head there bud, I think.
