Intel 102ggc:The Firmware has detected that Cmos Checksum Error

I assume that you entered the BIOS after replacing the battery and set the date and time? If you cannot get to the BIOS after receiving this message, it usually means that the BIOS has become corrupted, either by failure or by virus. You may be able to reflash it if you can download a bios update from the manufacturer.

Table of diagnostic beep codes compiled by AMI BIOS during power-on self test[8][9] Number of beeps

Meaning
1 - power-on self test successful
2 - Parity error in the first 64KiB of RAM
3 - Memory failure in the first 64KiB of RAM
4 - Same as 3, but also including a non-functional timer 1
5 - CPU error
6 - Error in the A20 line on the 8042 keyboard controller chip
7 - Generation of a CPU virtual mode exception signifying an error
8 - Read/write error when accessing system video RAM
9 - Mismatch between the calculated checksum of the ROM firmware and the expected value hardcoded into the firmware.
10 - Read/write error for the CMOS NVRAM shutdown register
11 - A fault in the L2 cache

TRY CLEAR CMOS IT CAN HELP.

Hi.

Exist some problems that can cause that:

1- The CMOS battery. Solution: Change it for a new one.
2- Some problem with the time specifications in the BIOS.
3- Some drive that isn't connected properly.

Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

CMOS checksum errors
Explanation: A checksum is computed as an error-detecting code, to protect the BIOS settings stored in the CMOS memory. Each time the system is booted this number is recomputed and checked against the stored value. If they do not match, an error message is generated to tell you that the CMOS memory contents may have been corrupted and therefore some settings may be wrong. BIOSes react in different ways to encountering this sort of error. Some will warn the user and then continue on with whatever settings were in the CMOS. Others will assume that the settings that were in the CMOS were corrupted and will load default values stored in the BIOS chip "for safety reasons". The error message will indicate which your system is doing.
Diagnosis: The most common cause of checksum errors in CMOS is a battery that is losing power. Viruses can also affect CMOS settings, and motherboard problems can also affect the stored values.
Recommendation: Follow the instructions in this section to address the CMOS corruption. You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values (hopefully against a recent BIOS settings backup).

this looks like you have kept the bios password and you forgot it. just do one thing open the cpu case to access the inside of the system and then just remove the battery in it. wait for 5 min and again plug in the battery. thats it your bios memory password will be reset.
2nd solution without removing battery. just reset the bios as shorting the jumper pins. consult your motherboard book to know where to find the bios reset. it will be written as CLEAR CMOS.

Hi there.
Basically you first bios update was bad, if you can get into the operating system re-flash the bios again, that will sort it out.

Good luck and thanks for choosing FixYa!!

Situation Remedies If you have encountered this error and would like to fix your computer, here are some remedies for each situation:
CMOS Battery Not Functioning Properly: If you suspect your CMOS battery is not functioning properly you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all settings are lost, you can usually get them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computers manual or tech support to remove your battery. Take down the CMOS batteries information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have remedied the problem.
Your BIOS has Been Updated (either by you or possibly a virus): If your BIOS has been updated recently, your CMOS settings may have become reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.
The Computer Was Shut Down Improperly: Sometimes when running MS Windows, if you shut down your laptop or desktop without first properly shutting down your operating system it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer before turning off the power. Usually this entails going into the Start Menu/ Turn Off Computer/ Shut Down. If you received the error, shut down the computer properly, if this is the cause of the error, the error message will not return.

cmos checksum errors are caused by a bad battery.
If that dont work then the board is bad from the factory.
