First thing I would do is look at Activity Monitor after shutting down and see which program is not responding. Try doing a Forced Quit on that program from the Activity Monitor. Usually this resolves my problem forever. Next I would check and repair permissions. After all that, if there are still problems, try reinstalling the last upgrade. The upgrade should go faster since it sees it has already been installed and only tries to install missing or corrupt files. No need to reinstall any applications, the upgrades won't effect them.
