Windows 7 - System event notification service error!!!

hi!

I am using win 7 home basic edition.
There was a power failure and could not shut down the system.
when i started the system it gave me this error.

Windows could not connect to the System Event Notification
Service service. This problem prevents limited users from logging on to the
system. As an administrative user, you can review the System Event Log for
details about why the service didn't respond.

i have also booted in safe mode and went to the command prompt in safe mode and did a netsh winsock reset.But still i am getting this error.does anybody know a solution to this problem?

Thanks
Mahesh

Try using system restore. I am quite certain that will resolve your problem

System Restore

You may try an sfc scan first, but I am not as certain about the results.

SFC /SCANNOW Command - System File Checker
