Most of the time you get a CMOS checksum error is because some of the data in the cmos is incorrect. That usually happens when you have a bad bios flash or if the CMOS battery is dead and doesn't save the settings that it should be.

As Mikeg says, it could very well be a bad battery. If that isn't it you might want to take a closer look at your Power supply. Those conditions match the behaviour of a "bad" or insufficient power supply also. Have you recently added any components?

well.. i doubt its a bad flash because the board did it right out of the box.. and another board i tired it with did the same thing... i have a 431 W Enermax psu.. and i got this problem when i switched cases to my koolance watercooled case 😀

Well then I'd think the answer is going to be found with the move to the new case. Could be a misplaced standoff shorting something. Are you using the water cooling now as opposed to using air cooling before? It's a pain but I think you should remove the board from the case and try running it sitting on anti-static foam outside the case. If it doesn't repeat the problem then you will know that it has something to do with the case/move. However, it could still be the PS. Maybe it is "going south" or maybe something is not hooked up right.
