You may need to reset the CMOS. Pull the new battery, and short
the pins of the holder for a few seconds, then re-install the battery.
You will probably have to reset all the options after this, of course.

Good Luck,

JOY, This was it but shorting it didn't work. leaving the battery out
all night did.
