Everytime I restart my laptop and try to login to my account I get the error of "Could not connect to system event notification service" which brings up a black screen and I only see the recycle bin icon on the desktop. I can access some files but mostly I am locked out of the entire system. I have to wait approximately 5 minutes and I can then logout and log back in and everything is back to normal. What would cause this? Is there a fix? I have tried multiple fixes and nothing has worked. Hope you smart people can help me!
