BIOS randomly resets to default settings

g0dFather
I have an older ECS P4S5A/DX v5.1A motherboard (circa 2002 model) that I used to build a gaming machine for my four year son. The motherboard BIOS will randomly revert back to its default settings for no apparent reason. I can set it up again and it can hold for hours, days, or even weeks. But at some point it will go back to default. It doesn't matter if it's starting from a cold boot or a reboot.

I've flashed it with the latest BIOS version more than once thinking that maybe it didn't take the first time. I've changed the battery. I've tried a jumper reset. I honestly can not think of any other reason for it to do this.

In default mode, the BIOS clock reverts to 100MHz and my 2.4GHz P4 runs at 1.8GHz. My son can't tell the difference.

Outside of letting the machine run 24/7, I'm not sure what else I can do. Any ideas?

Thanks in advance!

    Sounds as if the battery is low/dead and BIOS will revert to default when it looses the ability to save the settings.

    I'll buy another battery and give it a shot.

    If that doesn't work, another option I haven't tried is rolling back one version on the BIOS.

    I'm using v37498. There's a v37470 available. Both have the same release date. It's also worth a shot.

    Will let you know...thanks.

    Check your Motherboard Manual for the location. P4S5A/DX

    Use this jumper to clear the contents of the CMOS memory. You may need to clear the CMOS memory if the settings in the Setup Utility are incorrect and prevent your mainboard from operating. To clear the CMOS memory, disconnect all the power cables from the mainboard and then move the jumper cap into the CLEAR setting for a few seconds.

    2-3: Normal

    As already suggested change the Battery as you may have installed one that is not holding sufficent charge.

    I put a brand new Energizer CR2032 in the machine and it still randomly resets. It's an old board so I'm beginning to think it made be a faulty component.

    My next test will be to roll back one BIOS version and see what that does. Again, will keep you posted.

    If the battery is not at fault it is more than likely that the RTC Chip has gone bad. <br>
    If it doesn't matter to your son and it is only for games just keep it running as is. It will eventually fail its just that some of those older PC's seem to outlast the newer ones.
