Cmos checksum error is indication of a bad battery or corrupt cmos!

If you have changed out the battery and that did not solve it then yes flash to the latest official bios but remember to read about the proper before and after clear cmos proceedure when flashing.

 

P.S ....DO NOT USE WINFLASH!!!!! Also I say flash to the latest official because if that does not do it more than likely you will have to send the board in and get the cmos chip reoplaced or do it you're self! In any event just to be safe flash to a official in case it has to go too D.F.I for cmos replacement...OK
