Windows 7: Failed to connect to System Event Notification Service

This Error popped up on my Screen today



My Nvidia control panel, among other programs do not seem to start with windows any more ( i noticed this right away because my screen configuration had changed)
I have checked the service and all of its dependencies and all of them are working fine. a quick Google search yielded no fixes that worked for me and I'm stumped as how to solve this

Thanks In Advance

Usually it's a driver or COM component that's causing this. What does your Application and System event log show you as warnings or errors?

this is a freshly installed copy of windows, its only three days old. I installed all of the drivers from the manufacturer website, I have only installed Steam, iTunes, Avast, and origin.
This exact problem is sorta what pushed me to reload my system, that and it was getting sluggish. All my personal files and games are on a separate drive and a reinstall is not a big issue for me.
Below are the errors that i could find that have occurred since this error has popped up again, enjoy.

Errors That Occurs During or Shortly After start up

-Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

-The Windows Audio service hung on starting.

-The server {DCAB0989-1301-4319-BE5F-ADE89F88581C} did not register with DCOM within the required timeout.

This is a logged warning That occurs multiple times during startup

-The winlogon notification subscriber <GPClient> was unavailable to handle a critical notification event.

I am going to uninstall a couple of programs and reinstall some drivers, i hope its not hardware related because the system was just built a month ago

Thanks Again

The WMI error has been around since Vista, and is an easy fix:

The second error, the DCOM error (DCAB0989-1301-4319-BE5F-ADE89F88581C) is an NVidia service, so that would be driver related.

Given the other errors here, I'd install Windows but *don't install anything else* and see what sticks. I see you've got an NVidia video card, and the drivers for it are at least very possibly the root of your problems. Windows Update may install something (or Windows itself) during install, but don't attach it to a network or the internet if you reinstall, and see what you get there (keep WU from touching it during installation). Then, you can (one thing at a time, with at least 2 reboots between each component) layer things on. My money's still on the NVidia drivers though.

ill work on reinstalling windows this weekend, and as you suggest slowly reinstall drivers and programs. ill post my results when and if this error graces me with its presence again

Thanks for the help

Q1. is this a custom build? Yes/No.
Q2. Is SP1 (service pack #1) installed? Yes/No.
Q3. Do you have a Win 7 DVD? Yes/No
Q4. The source of your Win 7 is _____________________?

Provide 4 answers.

You made a decent start on your system specs. This will enable you to thoroughly fill out your system specs:
Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Ø Manufacturer and Model OR Custom build.
Ø ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

With Speccy, you can select with your mouse/touchpad info from the display
and paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

To answer your questions :
1. Yes
2. Yes
3. Yes, with SP1 on Disc
4. (if you mean, is it a legitimate copy) Yes, procured from NCIX.com

i have also added some more info to my system specs, i am at work right now and can't remember all of the details

this system ran for a few months with no issues, ran beautifully. destroyed every game i played across three screens. then all of the sudden that error popped up, nothing else changed, no new drivers or programs

this is why it has me stumped, I fell into a technician job at my local computer store and have seen a lot of strange stuff over the last year, but the fact that this showed up after a fresh install makes me wonder if its related to windows updates or failing hardware. ill continue with the windows reinstall this weekend and try to see when the error occurs

I'll keep you guys posted if i find out what the problem is/was

all answers good.

I have more questions, etc. but they can only be performed on your desktop.

So found out that my nvidia drivers wont uninstall properly, strange because i had been using these exact drivers from the beginning without any issue until this started

I am getting ready to reinstall windows, just downloading drivers for reinstall. if you want to ask any more questions now is the time

Why are you downloading any drivers? The only driver you might need to have on hand is for a WiFI or Ethernet connection, just in case, the Win 7 default driver doesn't do the job.

Remember: The installing of drivers started you into problems.

Win 7 is very smart. Install Win 7, then-without downloading and installing drivers-carry out the following:UPDATING YOUR WIN 7
1. ASSURE THAT YOU RECEIVE ALL UPDATES
WIN | type WINDOWS UPDATE | ENTER |
Change settings (left-hand column) |
checkmark all four of the boxes | OK button

Approve any dialog boxes presented. Let Windows install any update features.

WIN is the key with the Microsoft flag on top.

2. INSTALL CRITICAL UPDATES
Check for Updates (left-hand column)
Install ALL critical updates.
Restart your computer (even if not prompted)

Repeat this procedure until there are no more critical updates.

DO NOT TRUST the “Windows is up to date” in center of dialog. until you see that TWICE IN A ROW!

3. INSTALL IMPORTANT UPDATES
Use the “critical update” procedure until all important updates are installed.

4. INSTALL OPTIONAL UPDATES
Under Optional updates you will be presented with:
a) Microsoft Bing Desktop which is of questionable value
b) a list of about 34 language updates.

You can hide those updates so that aren't continually notified of those updates.
When you click on 34+ optional updates are available, then you
a) highlight all of the language updates,
b) right-click anywhere in the highlighted list.
c) click on Hide Updates,
d) OK button.
Install ALL other Optional Updates.
Use the “critical update” procedure.

UPDATE GOLDEN RULES
Install ALL, yes, ALL updates.
This is Win 7 and not Vista or XP (eXPired).

UPDATE IS HUNG –TAKING FOREVER
Hung is very doubtful unless you interrupted updates.

CTRL + SHIFT + ESC key combo will pop-up the Task Manager.
Lo and behold, Windows Update is still running!

You hold down the CTRL and SHIFT keys.
While holding them down, tap the ESC key once.
