Detailed explanation-1: -This could be due to installing an incorrect or corrupt BIOS update. The CMOS itself is powered by a dedicated battery, so you might also get the CMOS checksum error if the CMOS battery is weak, bad, or old. Power surges or improperly disconnecting your PC from a power outlet can also cause the CMOS checksum error.
Detailed explanation-2: -The most common cause of a checksum error during the startup process is a faulty battery that is not providing sufficient power to the motherboard when the computer is off. However, motherboard malfunctions and viruses can also contribute to checksum errors.
Detailed explanation-3: -Bad or old CMOS battery Reboot the computer. If the error still occurs after rebooting the computer, enter CMOS setup and check all values. Also, verify the date and time are correct. Once everything is verified and changed, make sure you save settings and then exit the CMOS setup.
Detailed explanation-4: -The most common symptom of CMOS battery failure is incorrect or slow system date and time in the BIOS, loss of BIOS settings when the computer is powered off, time-of-day clock stopped error message and so on. If the CMOS battery is out of charge, the BIOS settings will be lost when the computer is powered off.
