Sql server 2008 screwing with me ?? and help

Question

Hi fellas

1) Well it weird problem . from last 2 days i was unable to open sqlserver ... i am trying to give right credentials but its just showing me some stupid error i.e 

TITLE: Connect to Server

------------------------------

Cannot connect to (local).

------------------------------

ADDITIONAL INFORMATION:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

2) Well as some Google browsed pages suggested i tried to open SQL SERVER CONFIGURATION MANAGER . i am getting COULD NOT CONNECT TO WMI ??

So please help me .. feeling only option left is to re-install ??

TY
