Getting a CMOS reset (502) error

[TJDestroyer66]

I am receiving this error when I restart my computer, but it doesn't happen every time: 
The CMOS checksum is invalid. The CMOS will reset to the default configuration, and the computer will restart. Afterwards, please check the BIOS setup options to see if they change. CMOS Reset (502)
