Is this a CMOS checksum error? I think you need to go in to BIOS Setup - usually by pressing <del> immediately after turning the PC on. There should be an option to load defaults, then save and exit. If this returns then you will need to replace the CMOS battery on the motherboard.

I have tried that and no different response.it says bios recovery on screen, then stops ?

i should have said, i have not replaced the battery as the motherboard is only a year old. It should still be okay ?

It might help if you tell us exactly what you have done to arrive at this situation.

OK. Can you tell us exactly what happens when you turn your PC on, where the message occurs and what it says.

OK, either the BIOS is corrupted, or the CMOS battery is dead. I would change the battery first; they are usually CR-2032 button batteries and can be bought from most places you can buy batteries from (even Tesco). Find the battery on the motherboard and replace it with the new one. Once changed, you may get the same error. Go in to BIOS setup usually by pressing <del> or <F1>; it should say on the screen. Then find the option to load BIOS defaults, and Save and Exit. Strictly speaking the battery should last more than a year, but I have known them not to.

If your problem persists, then it may be that the BIOS has somehow become corrupt. You should download the latest BIOS update from the Asus website and follow their instructions on flashing the BIOS. This hopefully will solve the problem.

I have built 2 A8KV Deluxe systems fot others and from what my memory tells me this board has a crash free BIOS arrangement whereby you can recover to original state using support CD that came with Mobo.

I remember updating to BIOS version 1013 but I believe there have been more since to detect low speed fans and support higher spec CPU's.

Sorry I can't remember more as I didn't need to read up. If it's not a battery problem have a look in the
mobo manual as I'm sure you can
