Problem of mySQL in WinXP SP2

I installed mySQL database server in my WinXP SP2 machine. It was installed successfully. It could be started using command line mysqld -u root --console. However, It failed to be launched as Windows Services. I get error "Process Teminated Unexpected!". I tried to shutdown it by mysqld -u root shutdown, unblock it from WinXP Security Center but not help.

Anybody has any suggestions? I didn't get any problem to install mySQL in WinXPSP1 and Win2003 server.
