Question : Windows XP SP2 locks up frequently and event log erros are Sidebyside Event ID 32 and 59

I have a user whose machine is locking up every few minutes, the screen goes black and the only way to fix is by a hardboot.  In the event viewer for the System Log the following SideBySide errors are logged:
