Check the event log under Start | Programs | Administrative Tools (Common) | Event Viewer.
The event log is a very useful tool - if you had any problems during boot, you may be able to get additional details in the event log.
The event log can also help you identify security problems and a number of other system problems.
Events are coded in the event log by a color code. Blue events are for your information only. In a later exercise we will see some "non-blue" events.
