Event Viewer not showing up
What to do if the alerts in your Event Viewer do not show up? Try the refresh button in the Event Viewer. Usually this means there are too many events logged and your Event Viewer is jammed.
This happened to me after installing some new software that bunged up my machine.
Events were being logged like every minute or so and it shortly was overstuffed. I searched the net and found this suggestion in a TechRepublic forum and it worked. After refreshing I could see the events, delete the log if needed and carry on.
