    i have a refurbished MSI K7N2 Delta-L mobo, got it from newegg, so i guess that would explain why...
    every time i completely unplug my pc from the wall, i get the "cmos checksum error- defaults loaded, press F1 to continue". i thought it was just a bad cmos battery, but after having replaced it 4 times now with new ones, i don't think that's it anymore. i know i am installing the battery correctly, and the jumper cap is in the correct position, i have checked and rechecked the manual to be sure. is this maybe just due to a little bad wiring somewhere on the mobo?

    Have you tried updating your BIOS?

    A long shot., but replace that jumper. I have known a couple that have been faulty and not made the proper contact that have given that problem.

    You might also leave it on fow a few straight days. If the motherboard has been sitting on a shelf awhile, the battery tends to need a bit of charging. It's best to always leave a new build on overnight for this reason.

    The motherboard does not recharge the CMOS Battery.

    Kerri Ann pull the motherboard out and check for a cold solder joint directly under the battery cradle if you find one replace the joint. This is a common fault in some motherboards however 99% of these defects are found and rejected by the manufactures QA department you just got the one that got away. And in case your wondering a cold solder joint can work for years or just secounds, then fail compleatly without any warning.

    yes suck the bad solder out with a solder wick and resolder
    This statement is interchangable with replace the joint.
    and yes I should have stated replace the cold solder joint but I type with two fingers and one of them is blind:eek:
