The battery for your CMOS is getting weak and needs to be replaced.

Less common than the weak battery, parts of the information stored in CMOS that don't appear on the screen may have become corrupt. In this case, you can sometimes cure it by removing the battery for at least ten minutes but, most often in older systems, have to clear the NVRAM by setting jumpers or switches on the motherboard, powering up, powering down again and resetting the jumpers/switches, powering back up and checking all the CMOS settings again, making changes as needed.

I agree with answers 1 and 2, it is probably your CMOS battery. If this is an older motherboard, the battery may be soldered onto the board in such a way that it cannot be replaced. I would not suggest attempting to desolder and install a new battery, it's quite tricky. Instead, on most of these boards, somewhere near the on-board battery, there will be a set of pins where you can plug in a battery pack.

It could be the CMOS Battery, but there is also a jumper on the motherboard to reset the CMOS if this is set in the reset position instead of the normal operation mode it will produce the CMOS CHECKSUM ERROR this happens alot especially with new motherboards, just change that jumper and everything will be fine.
