Windows cannot connect to system event manager

If this problem has not existed for very long try doing a System Restore to a time prior to it starting.

Do you have more than one user profile on your system, if so, have you tried logging in with a different profile to see if the problem exists globaly or just in your normal profile? If the problem is with your profile only then this would suggest that the profile is corrupt and you should create a new profile if you don't have another already.

Another option is to run the System File Checker utility to determine if you have any corrupted or missing critical Windows files.

Lastly try temporarily disabling your AntiVirus and Firewall software then try to access the Event Viewer management console - it is probably best to have your computer disconnected from any internet access when doing this. If this succeeds then check for any events related to the error in opening the Event Viewer - you may find it easier to clear all the current events first then recreate the error and look at the logs again to identify the most current and relevant entries.

When using the right click on mouse or pad window explorer stopsand has to restarted closing the session

Normally explorer restarts due to over heating of cpu or if program is not closed properly. Some other reasons could be bad memory but in your case i am doubtful whether it is due to bad memory or hardware failure. You could try installing mouse drivers again. Instead check the event viewer for problem details. Start, Control Panel, administrative Tools, and Event Viewer. When researching the meaning of the error, information regarding Event ID, Source and Description
are important.

How to maintain windows event viewer. i was just made aware of the event viewer, and after reviewing it, i find i have many errors and warnings. do the errors indicate a security problem? do they...

You can safely delete the events from the event viewer; they are just for logging purposes. But you don't have to worry about; your computer by default is keeping the last months and overwrite the older events. The details about every error can be viewed by double click at the event, at the details area. About security problem - maintence: it depends on the errors; an error at "W32 time" that the computer was unable to correct the system's time, but an error at a local disk is critical and needs maintence; that's the reason for marking red X for the errors. In a few words, you just have to keep an eye at red X errors at "system events, all the rest informations can not be eliminated.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.

I get error rtl100.bpl what must i do

i am techbuddies from fixya group i would like to try and solve your issue .
please try to follow these steps

You probably read web pages written in a language that displays Right To Left
(hence rtl100) There are several reasons why that file might corrupt, an
add-on of some kind being the main suspect. Go to start/run, and type:

iexplore -extoff

to see it that stops the error.
If not, try refreshing all system files with :

sfc /scannow

if is doesnot work then try this

Are any devices malfunctioning? Select Start, All Programs, Accessories,
System Tools, System Information. Open Components under System Summary
and click on Problem Devices. Is anything listed there?

Are there any yellow question marks in Device Manager? Right click on
the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?

Does anything turn up in the Event Viewer Logs?

You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Run Event Viewer and double
click on the error you want to copy. In the window, which appears is a

Viewer.Now start your message (email) and do a paste into the body of

Hey i have a windows xp error. it says, stop:0x000c008E <0x00000005, 0x804ECESF, 0xEC3B0118, 0X00000000> and i can only boot in safe mode is there a way to fix this?

Have you attempted to run the MSconfig and remove anything not needed when booting into normal mode?

It sounds like you have an update to a possible driver or filter driver that could be causing problems the best way to solve this would be to do a clean boot stopping any services or applications you do not immediately need to get into the os?

Check the event viewer and pay attention to the system and application logs!

SUMP error in Windows Vista


Try to increase the size of Event Logs files.

Open up Event Viewer by typing in eventvwr into the Start \ Run box, or you can find it under Administrative tools section of Control Panel.
You’ll notice over on the right-hand side of the window that the current size of my Application and System Event Logs are 512 KB…

Now you can right-click on one of the Event Logs in the list, and choose Properties from the menu.

In this dialog you can do a number of things… you could clear the log, increase the size, or just set the system to overwrite events as needed

chose to increase the maximum size of the event log, and then also to overwrite events as needed

For those of you using Windows Vista, you’ll notice that the default settings in Vista are to overwrite as needed, and the maximum size is way bigger. Guess my setting choices make sense then…

All of a sudden vista home has started to blue screen with no predictability. I have run sys restore and also checked my antivirus but no solution what else can I do.

Well as soon as we can figure out the error,We can start fixing it,So,First do you have any usb devices(other than a mouse or key board), any memory cards,or even a disk in the cd/dvd drive? if so,Remove them and try to start in safe mode by tapping the F8 key while the computer is being started,If you get a boot option menu,Choose safe mode with networking and let see if we can find the error log.To do this,Click start>Control panel>Administrative tool>Event viewer,On the right screen,select the arrow beside Windows logs and it will open a menu,On that menu select,Application,When the list finishes loading,Go to the right hand side menu and choose save events as,Give it the file name Events and click the browse folders button at the bottom and select desktop as the save to location,then click save,When the pop up about language shows up,Check to show English,click ok.
Go back into the events viewer and do the same as above with the system under the same windows log as before and save to the desktop as before and give it the name Events2 .

Then email both to and I will see what we can figure out.
