what mobo are you using???
1. there is normaly a jumper on the mobo that you conect just for a few seconds then put back to normal this resets the cmos to default settings.
2. yes removing the battery and re installing will have the same effect
3. if it as an abit mobo with a soft menu then holding down the insert key on the keyboard during power on resets the the cpu settings to default.
hope this helps
