Vista - System Event Error

nikite@xxxxxx
I'm not sure if I am posting to the correct newsgroup so here goes nothing.
After a large update for Windows Vista Home Basic--restarting computer--a
box down by the task bar "System Event Error" appeared. What is this?? I
know nothing about computers so I went where it directed me--Event Viewer--
there is a whole bunch of stuff as errors and warning signs. Am having no
trouble with my laptop and seems to be doing what it is suppose to do
without any problems and the box has not appeared again (so far). The only
thing I can think of is I keep the User Account control "OFF". Since some of
the updates where vista and vista security, could User acct off have been
the problem??
What do I do with all of the error stuff in Event Viewer??--errors scare me
to death!! Thank you for your help.
