Windows 7: Windows could not connect to the system event notification service

Windows could not connect to the system event notification service

So recently I had hardware issues, and through warranty I had several replacements done. Mobo, Video cards, ram sticks, and the power supply.

After all that was fixed and replaced my computer seemed to have ran fine for a few days, and it still technically is except for this problem.

The problem is when I log in into windows normally it takes a while for Windows to boot up. I get a "Please wait" screen, then after a long 4 minute log in once inside windows I get the"Windows could not connect to the system event notification service", and the toolbar is grey all old school windows like.

The problem is the exact same as the issues found here except I am using Windows 7 64 bit.

In services the service is called System event notification, it says that the service is running fine. Even when i try to restart it, it makes no difference at all.

As for in event viewer. Im not to sure what to look for in there.

Ive looked at several familiar threads, I did the sfc /scannow twice, i did a windows start up repair, I disabled all non-windows services, and even just tried restarting the service in services.

I'm not really sure what to do next. I'm tempted to just to do a clean install. However I am cautious on doing so, in case its some kind of hardware problem...

Anyway do any of you have any recommendations or other possible solutions I havent tried yet?

Thanks in advance.

Through your post, I seemed to have missed your actual problem. Is it the system notification service in your title?

What are the particulars of the Event Viewer Error messages about that occurrence?

Sorry about that. Somewhat stressed from this. Anyway I fixed my OP, everything I added to OP is in this message.

In the Event Viewer, look for Errors, or perhaps even info, around the time you boot your system. That would be the best way to tie particular errors to the problem.

You can highlight each error and expand it to see if any text is included describing a problem. From the other threads you linked, some services may be involved. Or maybe even some anti-virus is blocking the communications.

Check the Action center (white flag) and see if anything is being mentioned there.

Well this time it took even longer to log in. After "Please wait..." it left me with a "Preparing your desktop..." screen. In which once i logged in my background was black, toolbar still grey and had an error message saying "Location is not availble. It could not find my system profile. C:\\Windows\system32\config\systemprofile\Desktop refers to a location that is unavailble. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the internet on your network, and then try again. If it still cannot be located, the information might have been moved to a different location".

Also the failed to connect to windows service popped up as well.

While replacing parts on my computer, the technician who came through warranty may have unplugged my disk temporarily.

Is it possible that this is what is causing the issue? That the HDD is not connected properly? I have gotten this issue twice now (all within 24 hours). Though it is not consistent as my system event problem.

So I rebooted since I cannot do anything when that happens. Went into safe mode and checked event viewer.

In event viewer I have 18 errors of ID 7001 Service Control Manager- "The network list service, service depnds on he network location awareness service which failed to start because of the following error: the dependency service or group failed to start.

I also have 6 ID 10005 DCOM errors. "DCOM got error "1084" attempting to start the service WSearch with arguments""in order to run the server: {9E175B6D-F52A-11D8-B9A5-505054503030}

I also had a few winlogin warnings that failed to handle a critical notification event.

Lastly the whiteflag thing didnt have anything useful to tell me. Nothing new in there.

Try running system file checker.
In the search box enter CMD, right click on cmd.exe and select Run as Administrator. Enter sfc /scannow at the prompt. It will check and try to repair system files.

I've done sfc /scannow, and have found no issues. I've done it twice and did a mandatory check when i booted up my PC once. I did all the scans within 3 hour time period.

This is getting above my pay grade, but while waiting for help from a more experienced poster, try this.

Go to Component Services > Services (Local) and find the services that event viewer lists. They should be started or automatic. Right click on the service and select Properties > Dependencies. Be sure all the dependencies for that service are started or automatic.
