Windows could not connect to the System Event Notification Service

[cgentil]

Hi,

I got this error Windows could not connect to the System Event Notification Service service.

And nvidia control panel doesn't start up.

Problems:

- Slow startup ("please wait" before login screen)
- NVidia Control Panel isnt working

Some Windows Updates was done yesterday i don't know if it's related.

Please help.

KB3097877 has been causing all kinds of problems. You could try removing it and reboot. Then see if you still are having problems.

You can always install it again later if need be.

Will try.

Still same!

A couple of things to try. They may or may not fix the problem.

Pick a restore point before this problem occurred.

So we can have some more information about your system.

Please complete this tutorial also by Brink.

1. What do you have plugged into your computer other than mouse and keyboard?
2. Is this computer on a domain or network?

Running sfc/scannow.

It's something related with NVidia because the NVidia panel can't be opened, but if I end my session and login again all works normally.

Very abnormal.

Well, I can login and all goes well, but until login appears the black page blink once and then appears the login, it wasn't happening before, anyone have any ideia? I know it's a minor thing but would like to fix it, because it wasn't blinking. Already uninstalled the update from computer. Windows 7 x64.

I'm glad things are going well.
Would be nice to see your system specs. Your (My System Specs) will follow your every post.
Which process (tutorial) saved the day?

I don't know what is causing your blink of black screen.

 

[cgentil]

Well

I went on msconfig, disabled all services and startup apps, then restarted, then activate all again then problem gone.

Until now all is ok.

I will put my systems specs.
