CRITICAL EVENT ID 100 found this when trying to evaluate very slow boot time.
How can I resolve this critical problem without doing a complete re-install ? My boot time is more than a minute running Vista Home Premium on a Gateway GT5654.
I am running Norton 360.
In relation to the Norton, one of the other system reports I ran showed
that Windows Security shows no spyware or virus protection enabled though I have Norton 360 turned on.
Maybe this is causing a conflict which is related to the Critical Event 100 boot problem.
Please help, let me know what system info I need to post and HOW
to post it so that you can evaluate my problem.
Thanks in advance.
