win xp service pack 3 problem

Hi, has anyone else experienced any problems with XP service pack 3? I received it as an automatic update - followed the instructions and closed all running programs (inc AV) It seemed to go ok and got to the dialog 'Finishing Installation' The status bar got about 3/4 through and appeared to stop, but windows reported it as a running process, so I left it to run overnight, thinking it was just slow. About 9 hours later, the status bar had not advanced and the program reported as 'not responding'. I couldn't stop the process, no programs would work and the pc wouldn't shut down. I switched off manually, and re-started, with the message that the 'installation had been interrupted', and to re-install, but nothing would work, the task bar was unresponsive and not even system restore would run. I re-started in safe mode and managed to restore the system to before installing SP3 and everything is now good. Is SP3 dodgy, or did I just get a bad download??

thanks
pete
