Happy New Year Bill. Sounds like your CMOS battery may need replacement. Almost always it's a CR2032 button cell. It supplies power to your CMOS memory which stores all the BIOS settings that are user changeable. It's a fairly easy fix just remove the old battery and replace it. The only thing is when you power up your system all the settings will need some adjustment. Your best bet is to choose default settings (or something in similar terms, varies by BIOS supplier) and then set the current time and date. If you need something further do a web search for your particular system or motherboard.
The battery should be visible when you remove the cover of your system (although I just had to take a Dell Optiplex 7010 MicroFF completely apart to get to the CMOS battery but that's a rare exception).
Here's a pic of the battery. Good luck. It's a pretty straightforward fix.CR2032.jpg

Yeah Bios Battery! Change it. Good luck.

But the picture shown is for desktop and some laptops, most laptop have a shrink wrapped battery on a molex connector, you didnt say if it was a desktop or laptop. but check your model do a google search, it will probably show you what type it has. Again, Good luck!

That's true. However once you start digging into a laptop BIOS sometimes you are opening up a can of worms. Rarely a laptop BIOS so straightforward as a routine tower/desktop MOBO and even then there are exceptions. Laptop and the exceptions can and most times will store at least some of their settings in NVRAM. Some Dell and Lenovo desktops are exceptions.

These settings to go from a few security settings to in some cases extremes. ThinkPads are a great example of extremes and anyone who has dealt with them know exactly what I am talking about. The point here is just for informational purposes. You just can't remove the CMOS battery to reset settings stored in NVRAM, admin passwords are a good example but can be far more than that.
I am not trying to start a discussion I just thought it was a good chance to let those know who might be curious. That is one of the goals of this board. NVRAM is almost always a huge pain and the first few times you run into it can be very frustrating.
