Windows uses the Windows XP event log to keep track of a number of significant occurrences in the system and in programs. It does this in the background, so you won't notice anything until you open up the event log for inspection.
The Windows XP event log is an excellent starting point when troubleshooting your pc.
Everyone should inspect the event log from time to time. It can reveal amazing possibilities for improvement, you might be surprised. Even on a pc that sings.
There's always room for improvement.
Use the event viewer to inspect the contents of the event log :
Windows opens up the event viewer.
In the left part of the screen, you will notice (at least) three types of logs that Windows XP maintains :
Now click the system log in the left part of the screen. On the right side (in the details pane) you will see a list of generated system events, organized in several columns.
You can click on the column headers to sort the columns. Click again on the same column header to sort in the other direction.
You may feel a bit overwhelmed by the overload of information here and by the possible occurrence of yellow question marks (warnings).
There are basically three types of events : information, warning and error.
There's no need to worry about informative events : they just, well, inform you that something has happened, e.g. a driver has loaded or a service has started.
Warnings : not critical. May be an indication of future problems, for instance when disk space is running low.
Errors : you should try to get rid of those. They indicate a significant problem, such as the failure of a critical task. For example when a system service fails to start. These can cause loss of data or functionality.
If you have isolated an error event in the Windows XP event log that you want to address, double-click the event in the details pane of the event viewer. Windows opens up the event properties dialog with detailed information about the event.
It's beyond the scope and possibilities of this article to offer a solution for every possible event in the Windows XP event log. You can note the event ID in the event properties dialog and perform a search for that event ID in Google or your favorite search engine to get started.
To improve your understanding of the event log, richt-click on "Application", "System" or "Security" in the event viewer and select "Properties". Windows opens this properties dialog :
Here you can track down the system file that holds the event log info. This dialog also allows you to manage the maximum size of the event log and the action that you want Windows to take when the event log is full. The default setting is that events older than 7 days get overwritten.
