CMOS Checksum Error: Defaults Loaded

Okay. This is what happens. Every time i use my computer for the day, shut it off and go to sleep, something wierd happens. I wake up, turn it on, and i get a "CMOS Checksum Error: Defaults loaded". When this happens, my boot up process screws up, and it comes up with a NIC ethernet thing that is trying to find my GUID and gives me my mac address. After that, it says system boot failure, insert system disk and press enter. So i do that, and it keeps saying insert system disk and press enter. The only thing that i can do to fix this is to load the "Fail Safe defaults" in my bios. I have a VNF3-250 Chaintech Zenith Value Board. I also have Phoenix Award Bios on my motherboard. Can anyone help me resolve this problem?

Your motherboard has a battery [with a special model number on it] that looks like this. It needs to be replaced. You can purchase them cheap at your local Radio Shack or electronics store.



For my motherboard, the battery model is CR2032. I think this is standard, I'm not sure.

Make sure to replace it when the power is off of course.

I got the motherboard about 20 days ago. does it still need to be replaced?

replace it to be sure

if you are lucky that will fix it

Yes but they may have been stored in a warehouse or factory for quite some time. Most likely a faulty battery.
