help me! my mssql 2000 server (with sp3a) is keeping full loading my cpu non-stop now!

my mssql never be used much
and i had a firewall to blocked the port of mssql to internet

but i don't that why tonight the sql server non-stop keep full loading the cpu suddenly until now!
please help meSQL Server 2000 SP3a is nothing but 10.5 megs of Transact code, if you send me an email with the in my profile I can help you with it. That is some of the most clean and close to ANSI SQL code I have seen from Microsoft. You may want to ignore some of the questions Windows ask you answer only those relevant to you. I write ANSI SQL, Transact-SQL, Java and C#. Hope this help.

Kind regards,
Gift Peddie|||do u have any msn messenger then?|||No I don't do messengers, what I can tell you is there are 25 files and Windows will only execute the files applicable to you because only 11 files were executed on my Windows 2003 Enterprise Server that was not part of a network. But with SP3a I was able to install Reporting Services and Analysis Services without problem and I had Visual Studio 2003 on the box before SP3a. Hope this help.

Kind regards,

Help me get MSDE SP3a installed on Win Server 2003

I've tried every which way I can from the docs and but I can't seem to get MSDE to install correctly. Found out that Win2003 only runs SP3a, downloaded and tried it.
tried these different commands from the prompt:
setup SAPWD="xxxxx" INSTANCENAME="xxxxx" TARGETDIR="xxxx" (from MSDE2000 only)
setup /upgradesp sqlrun INSTANCENAME="xxxxx" DISABLENETWORKPROTOCOLS=1 (after installing MSDE2000 first)
setup INSTANCENAME="xxxxx" SAPWD="xxxxx" (straight from MSDE2000 SP3a)
Services shows that the SQL agent and the MSSQL$xxxx running. MSSQLServerADHelper is not running. The Service Manager isn't showing any services in the tray nor does it have the little green arrow. I can't connect to anything with Enterprise Manager eithe

What do I need to do? Please note, I'm a totally complete noob with SQL admin and set up...
Thanks...
PS: and note that I'm in the correct directory with the installer and the xxxx are the correct instances and pw's
addition: This is Win 2003 Server Standard Edition...
