BleepingComputer.com: Event viewer

In my vista event viewer I found many diagnostic problems.Event ID 100 is critical and it is related to boot performance. Every time I start or reboot my Inspiron,I can find same:event ID 100,diagnostic critical,boot performance related.There are few other,always the same IDs with warning or critical diagnosis.What is it?Is it serious?How I can fix it?
Thank you

What are the details of the warnings?
What do you see when you go to Start and type in "perfmon /report" (without the quotes) and press Enter?

When I press start button,there are following options:default programs,windows update,programs,documents,settings,search,help and support,run,shut down.I entered in run space what you said,but no findings.Will you,please,give me more detailed instructions?
Thanks

To get the details of the errors, double click on the error and it will give you more information.

As for perfmon /report - you've gotta type perfmon, then a space, then /report in the search box that appears when you click on the Start button. Press Enter after doing that and a report should run.

Yes,you are right about double click,it displayed more information with the option to send to microsoft.I did it but no findings about problem.I typed as you said in search space,click enter but nothing happened.What ese I can do?

hi,,, you need to start to backup everything to dvd's or external hdd just incase it goes west,,,, if you have an external hdd,, try booting with it unplugged,,, see if this helps,,

I'm also experiencing this. The below should give you some idea of what we're dealing with.
It's not crippling my laptop (vista, inspiron 1520, 2GB, 2.0ghz, sp1), but I'm concerned it's slowing things down.
Here's an event viewer log:

Also one with an event ID 400:

There were a couple more event ID's scattered here and there, but these two are the most common and most recent.
Any help would be appreciated.
