It sounds to me like your CMOS battery is probably dead. This is usually a button cell type battery located on the motherboard somewhere.

If this is a desktop PC, it should be pretty easy to replace. However, if it is a laptop, it can be quite a chore. I recently replaced this battery in my Mom's old Compaq laptop, and to do so required me to take the entire thing apart to remove the motherboard. Some other laptops make it a little more accessible though.

your response is correct.

This is most definately a battery issue. In some cases, the battery may not be able to be replaced on the motherboard. For some motherboards, its built-in and not field replacable. Most motherboards will have the option to allow you to replace the battery.
