On your motherboard you'll find a coin cell battery (the CMOS battery). That battery is likely either disconnected or dead. You can fix this by replacing the battery and making sure it has a solid connection.

 

Usually they're a CR2032 battery. You can get them for a dollar or two.

 

It's also possible that your motherboard has two jumper posts for resetting your motherboard's BIOS, the jumper could be on those posts, or something else could be shorting them causing your BIOS to reset. I haven't seen these on more modern hardware though.

How old is your motherboard?  Perhaps replacing the CMOS battery will fix it.  Or maybe something is hitting the CMOS jumper in the case?

Replace the battery on your motherboard and stop unplugging your computer from the wall (or using the power switch in the back of your power supply).

 

Computers are designed so that even when they're turned off, the power supply give a bit of energy to the motherboard

Among other things, that energy is also used to keep the settings preserved... so the battery is not used when electricity is available from the power supply.
