This error message indicates a corrupt registry.

Start the PC and when it begins to initialize, start tapping the F8 key
continuously until you see a boot menu. Use the arrow keys to select the
"Last Known Good Configuration" option and press the Enter key. This should
fix the problem.

If not, take a look at the following information:
