Hi all,
Can som1 help me?
I have a asus p5n-d mobo, that keeps giving the same error at start up " Cmoc checksum error - Defaults loaded". Ive updated the bios file from 0601 to 0801 and also changed the battery but I keep getting the same message.

Ive tried to reset the bios with the mobo cd but that aren't no help either.
If their arent anything else I can do, im thinking of getting a budget socket 1155 mobo with sli, could som1 recommended a mobo.

Thanks

Hi

take a look here - there is some useful info that you may ( or may not ) have seen before
click here

"Defaults Loaded" seems to imply that the BIOS is functioning OK .......... just back to default settings.

When you get the error - can you boot up ?

Did you change the battery for a new one?
Often this message is linked to a dying battery.
Were your date and time settings correct prior to the problem ?

Hi, thanks for your help.

I can boot up after i choose 1 of the 2 option i get under the error message. cant remember the correct words but, press 1 to continue with default setting or press 2 to enter bios settings.
I didnt get a new battery but just replaced it with a another 1, will need to get a new 1 soon.
i can set the date and time in bios setting and restart the pc but get the message again when starting the pc again, so it happens every time i start the pc.

I only use this pc as a media pc to watch movies and uplad music to my ipod.

PC spec;

Asus P5N-D
intel 3.4ghz
4gb ddr2
nVidia Geforce 9600 gso 512mb
Win.7 x64bit

Thanks again for your help.

Hi, KenB may not get back soon as he is away from home, however if you are having to reset the time and date each time you boot up, then yes you need a new battery, it looks like the one you tried is also flat.

Hi
my connection is intermittent ( not at home ) so may not be able to reply every day.

As Nev says - try a new CMOS battery.
They are quite common and you can pick one up in Halfords / Jewellers / some supermarkets too.
It should be a CR3032
The + shows on top when assembled.

You will need to set the date and time after replacing the old one.
