when the PC was on-ed, it was in english , after sometimes, the language turned itself to that language

I moved this to a new thread as it is a different problem.

However with all of your problems it might be a sign of deeper connections.

Did you get your HijackThis log resolved?

Did you run some hardware tests?

At some point you might consider a Repair Install of XP.
