I used to have a similar problem with XP, but it was more to do with my mouse software. After using my pc for a while it would all of a sudden reboot itself and then continually BSOD. The only solution I could find was to totally remove all my Logitech drivers for both mouse and K/B. Now I never get the reboots or bsod screens, so it may be a problem caused by recent software program that you have installed or a recently updated drivers.
Try removing any recently installed hardware software/drivers and then try burning a cd. If not try other burning software to see if they cause the similar faults with xp
