Windows 7: Could not connect to the System Event Notification Service


12 Apr 2012   #1

Windows 7 Ultimate x64
 
 
Could not connect to the System Event Notification Service

I have tried each and every one of the solutions on the forums and over here. All my drivers are up to date (double checked), I rolled back and uninstalled all updates, Did sfc /scannow three times and they passed without any integrity violations. I've tried netsh winsock reset as well. The aero is gone, greyed out plus I can't select any other theme and whenever I start up the computer it displays the message "Could not connect to a Windows service".

This started happening about 2 months ago when my laptop ran out of battery in hibernate mode. It didn't resume so I had to press the power button again and then it took about 8 minutes to boot with nothing but a black screen and the mouse there. The audio service isn't running every time I boot up (I have to right click and run troubleshooter to start it).

Does anyone have ANY idea what might be causing this? How do I fix it? I've uninstalled all the software that I installed before the error occured as well.

I'm using Windows 7 Ultimate on a Sony Vaio VGN-NW25GF. Intel Duo core T6600 and the ATI Radeon HD Graphics 4570 card.

I would try a Repair Install as a last resort before running Vaio Factory Recovery from its partition - make the backup disks first as a secondary backup method.

However most tech enthusiasts want the better performance of a Clean Reinstall - Factory OEM Windows 7 using the Product Key on COA sticker. Everything you need is in the tutorial.
