Do you have Norton AV installed on this computer? If so try updating the symevent files:

Symevent files are automaticlly installed by running sevinst.exe for Windows 95/98/Me/NT4/2000/XP/2003 (32-Bit) only. The current version of the Symevnt installer (sevinst.exe) is 11.3.0.22. The installed files are version 11.3.0.17.

If that doesn't work, uninstall the AV and find an alternative.
