BIOS resets itself.

Ok I've been having this problem on and off for a while. I have a ECS K7S5A, the BIOS is the newest release. After I shutdown sometimes, when I turn the computer back on the BIOS is reset and I have to go in and re-setup the BIOS, the time and everything. It doesn't happen all the time. Maybe once every 2 weeks it seems. I've just been going in and fixing all the settings but its starting to get annoying. Any clue why it would do this? I don't think the battery is going bad, but I don't know. It only happens after a shutdown never after a reboot.

I would replace the battery first and see if that takes care of the problem.

Yep, had this problem on a new Biostar board that I put in the kids PC. Doublecheck the CMOS battery if it's fairly new to see if it's fully seated. Mine wasn't and this was the cause of my problem. Whenever I got a checksum error and the CMOS reset to defaults, the clock would be off also. We're talking way off here, like 1999.

I did a Google a while back and noticed a few hits that said that bad memory could also cause this? Might be worth a look. If you have 2 sticks installed you might remove one and run the PC like that for a while. If the problem continues switch to the other stick until you have eliminated your problem.
