Bios Resets on Rampage Formula Motherboard

I recently changed video cards from 2 x 4850s to one 4870 and since then I have been having some problems. When I go and turn on the computer in the morning I have to input all my bios settings because everything gets cleared including the time. The thing is that the computer is fine during the day even with restarts but the bios only gets reset during initial boot. Do I need to change something in the settings because of the new card?

I also noticed that I cant synchronize the time with windows server in windows. By the way I am using bios 0902.

The only thing I know of that would cause that would be, a motherboard battery dying.. but that has nothing to do with video cards.

seems unlikely as they usually last 5+ years.

Thanks badge I will try that. But first I am going to try what Asus tech support suggested. They said to check the cmos battery with a multimeter when I turn off the computer tonight and then check it again before I boot it up to see if the battery is being drained.

My ASUS board would power on randomly, like overnight. The prompt that the BIOS settings had changed press F1 to enter BIOS and make adjustments would show up on boot up. The BIOS would be defaulted and the clock had to be reset each time. Replaced PSU and that fixed it. Still running fine today with new PSU.

See the stickies on the Asus Forum (site down atm)
