Your CMOS configuration table is corrupted. This will happen
if your battery is worn out. It can also happen if a program
runs amuck. It can also be caused by hardware failure.
Run SETUP to rebuild the table. If that does not fix the problem, 
replace the battery and run SETUP to rebuild the table. 
If that does not work you have serious hardware problems and it's 
time to visit your local repair shop.

The location of the battery inside your system will vary depending on
whose system you have but it should be a 6V lithium battery. I have
seen systems where the battery was stuck to a convenient flat surface
with velcro and systems where it was hidden in a container that
had to be pried loose. Take off the cover and follow the wires
until you find something that looks like a bttery or might contain
a battery. Electronics parts stores should have replacement
batteries.
