The cause is obvious! your CMOS battery has ran out!!you should buy and replace the backup battery of your CMOS (Usually on mother board).Your computer can not keep CMOS data and also the built in real time clock of your mother board does not work any more.and the solution is just replacing the battery with a new one.
