CMOS setting Wrong

[Perrogative]

hi there, i am a noobie when it comes to CMOS. Recently whenever i start my computer, the startup screen will display CMOS setting wrong and time not set correctly. And i will be prompt to go to setup page to set the timing before starting the Window XP. Why is this so? Can someone help me? Thanks in advance.

It sounds very much as if the CMOS battery is needing replacement.
