Post back if you have any questions and your progress on these steps

was this service pack installed on an exisiting old xp install? If so, the majority of ppl here will agree that installing service packs on a fresh install of xp is always the best way to go. SP upgrades on existing installs is like gamble to me. With all the stray files, drivers, registery entries/errors, multitude of applications installed, previous multitude of apps installed, malware, some types of AV scanners/apps getting in the way of SP installs, severely fragmented HDs etc etc etc etc etc can all get in the way of service pack installations. It could of been one program that could of caused the problem, OR it could of been a combination of problems that could of done that. Always do SP installs on a fresh install of any os you have.

Uninstall SP3, then see if it works. If it does, you do not need SP3 for anything anyway.
