Reports Services installation problem.

In my laptop, I got W2003 server Std, Sharepoint portal, SQL 2000 and SQL 2005.
After I have trouble to run the Http://server/Reports. I applied SP1, then I
under install the SQL2005, but failed to remove the Reporting Services.
Then I re-install the SQL 2005 with a new instance name, then applied SP1.
when I start the configuration using Reporting Services Configuration
manager, I received an error.
"An unknown error has occurred in the WMI Provider. Error Code 80040219."
Is there any way that I can re-install SQL 2005 with Reporting Services
without re-install the machines?About Reporting Services and SharePoint on the same server, read the article

Windows SharePoint Services

About SQL Server: Can you uninstall the whole SQL Server? And then reboot.
And then install SQL Server 2005 with Reporting Services from scratch?
